In recent years, a new soilless growing technique has attracted attention. Staff only need to water a sponge planted with plants, you can realize the planting.natural dish sponge This sponge is known as the "planting sponge", it is made of polymer foam material and a certain proportion of organic or inorganic material mixed foam and become. Through the chemical structure and three-dimensional network crosslinking system, planting sponge has chemical and physical stability. It has high open pore rate, lightweight material and more than 97% open pore rate. Under weak acid and alkali environments, the planting sponge will not age, decompose and has no residual free formaldehyde. In addition, planting sponge also has the characteristics of environmental degradation, can decompose plant growth elements and conducive to the growth of the root system, so it has been a basic alternative to soil.

It is understood that the planting sponge is not limited by the convenience of the site, not only can be placed on the ground, but also can be placed on the wall or roof for planting. It is one of the advanced cultivation modes in current agricultural production. The use of planting sponges to grow green pollution-free vegetables do not contain any pesticide residues, and their taste and nutrition than ordinary planting vegetables. The fertilizers used in the planting process are soil-less nutrient solution, which is characterized by cleanliness and hygiene. The project of planting sponge green pollution-free vegetables is not only suitable for factory mass production, but also suitable for urban residents to plant on their balconies.

In terms of cultivating seedlings, nutrient bowl seedling or artificial substrate soilless seedling can be used. As for aerosol cultivation, it is best to use aerosol seedling method, which is a soil-less seedling technology with the advantages of early sprouting, high rate of sprouting into seedlings, and rapid and robust seedling growth. The sprouted embryonic roots are placed in the nutrient fog, which can rapidly absorb nutrients and promote the extension of cotyledons and the emergence of true leaves. Moreover, the root system grows in the air without any friction resistance, and the root system is intact and undamaged when transplanted, so it is possible to realize the effect of transplanting without slowing down the seedling and without damaging the root system, and it is a true net-root seedling.

If you want to plant in water, the process is not as simple as planting vegetables in soil: first, take a piece of sponge with a thickness of 3cm or more, and then cut it into a crosshatch with a depth of about 1.5cm. Then bury the seeds in that 1.5cm and submerge the sponge in 1.5cm deep water. After a day or two, the seeds will germinate. After about a week, when the vegetable seedlings have grown to 4 leaves, you can wrap 4 to 5 seedlings in the growing sponge for transplanting into a hydroponic container. During the growing process, you need to pull out the weak seedlings and leave two or three healthy ones at the end. It is enough to change the water in the bucket every two or three days. Vegetables grown this way do not need to be sprayed with pesticides and are very green and environmentally friendly.

Can I still buy insurance if I have cancer? There will just be restrictions, such as critical illness insurance, medical insurance,Cancer insurance accident insurance and so on are not necessarily available. What should I do if I have cancer when I didn't have insurance awareness before, or before I had the chance to allocate insurance? Can you buy insurance if you have cancer? Don't worry, the following small talk.

First, can you buy insurance if you have cancer?

1. Basic social security: including social security for urban and rural residents, social security for urban workers, and social security for flexible employment, all of which belong to the national welfare insurance protection, and have not made any restriction on the physical health of the insured, so even if they have cancer, they can still buy it;

2. Universal supplemental medical insurance: Most of them can be bought as long as they have local medical insurance, and there is no restriction on age, occupation, household registration, physical health, and no need for medical checkups, so cancer patients can also buy them;

3. Tax-advantaged health insurance: there is no requirement for the health of the insured,Term Life Insurance as long as the insured is over 16 years old and has not reached the statutory retirement age, and still pays taxes, then even cancer patients can also be insured;

4. Financial insurance: limited to financial insurance that does not involve death and health protection, which generally has lower requirements on the insured's physical health, so cancer patients can also buy.

Besides, if cancer patients want to take out health insurance such as critical illness insurance, they may not be able to do so:

1. Accident insurance: Most of them do not require health notification, so cancer patients can buy them. However, if the accident insurance requires health notification, then although it is more lenient, it will usually refuse to insure patients with malignant tumors, which means that cancer patients cannot buy it;

2. Critical illness insurance: most of the cancer patients are unable to insure critical illness insurance, however, if it is thyroid cancer, early breast cancer, prostate cancer, then the patient can try to insure it after 5 years of healing, and the health notification of the more lenient critical illness insurance can be excluded from the coverage in general;

3. Annuity insurance: belonging to financial insurance, some do not require health notification, so cancer patients can consider taking out insurance. If the annuity insurance requires health notification, it usually refuses to insure against malignant tumors, which means that cancer patients cannot buy it;

4. Life insurance: health notification is more lenient, although the malignant tumor patients will refuse to insure, but if it is thyroid cancer, early breast cancer, prostate cancer patients, post-operative recovery has been more than 5 years, then life insurance can generally be underwritten at an additional cost.

Second, can I buy insurance for cancer?

Of course, cancer can be insured, social insurance does not have any restriction on this, while commercial insurance needs to be based on the type of insurance.

Social insurance, needless to say, has no age limit, no occupational limit and no health condition limit, so anyone can be insured. As for commercial insurance, most of the cancer patients can't be insured in the types of insurance that require strict health notification such as critical illness insurance, multi-million dollar medical insurance, life insurance, etc., while there are possibilities for cancer patients to be insured in the accident insurance and financial insurance that don't have any requirements on diseases. Therefore, we must take out insurance before it's too late, don't wait until you can't buy insurance but need it.

But in fact, although the nano dishwashing sponges produced by regular manufacturers contain formaldehyde, their formaldehyde content meets the requirements of the production specifications.wholesale loofah suppliers In addition, formaldehyde is soluble in water, the formaldehyde content will be gradually reduced after a period of time. Therefore, the use of nano-sponge dishwashing does not cause too much harm to health. If you are still worried about it, you can use the nano sponge to scrub shoes, furniture and other household items instead of tableware.

3. Precautions for using nano sponges

Nano sponges have strong adsorption ability, so you need to pay attention to the following situations when using them:

(1) Painted electronic product screens: Computers, TVs, camera lenses and other screens should not be scrubbed with nano sponges, so as not to wipe off the coating to affect the use.

(2) electrical products: If you use nano sponge cleaning electrical products, be sure to wring out the water before scrubbing, and wear insulated gloves when scrubbing to prevent electric shock.

(3) leather products: due to the nanosponge adsorption capacity is very strong, easy to make the color faded or stained leather products in an inconspicuous place to try to wipe to determine whether or not to apply.

(4) oil particularly heavy places: range hoods, stoves and other areas of heavy oil, although the use of nano-sponge can remove oil, but it may also lead to thick oil and nano-sponge closely adsorbed, difficult to clean. In this case, it is recommended to replace the nano sponge with a new one.

To summarize, nano sponges can be used for dishwashing, and they can be used with only a few specific conditions in mind.

Polyurethane sponge is a kind of low-density polyurethane with a foam density less than 18kg/m3. It is usually made with more than 4.5% of water (100 parts of polyol), more than 55% of TDI and vacuum foaming. During the foaming process, the foam cell has to withstand the atmospheric pressure,Konjac sponge company the weight of the foam, and the gas expansion force. Under the condition of 4.3 parts of water (per 100 parts of polyether polyol), it is possible to produce a propriety foam with a density of about 24 kg/m ~ 3 .

When the external pressure is reduced to 0.05 MPa, the same 4.3 parts of water can make a bulk bubble with a density of 16 kg\\u002Fm3. It is worth noting that the rise and solidification time of the foam must be adjusted appropriately, i.e., the rise time should be extended and the solidification time should be delayed in order to ensure that the foam has sufficient foaming opportunity under negative pressure. For continuous flat-top block sponge, the equipment investment of "negative pressure foaming" is large, which is difficult for small and medium-sized enterprises to bear,karesponge but the investment cost of "box foaming" is not too large. Suggestions: build a cylindrical vacuum chamber, looks like a "vacuum drying box", plus a large pumping capacity of the vacuum pump to ensure that within 30 seconds can reach the required vacuum.

In operation, this teaching method is feasible. As long as by controlling the foaming time is not more than 30min, the large piece of foam will be moved into the forced cooling room, so that the foam economy continues to mature, can be realized to achieve the purpose of the design. The technology is very suitable for China's domestic development of large and medium-sized enterprises, investment in environmental transformation costs less costly,bulk sponges for cheap fast on the horse, but the polyether production equipment manufacturers to cooperate with the management of the work, to develop a special varieties in line with the high volume of water and low density PU soft foam.

Liquid CO2 foaming technology liquid CO2 (LCD) foaming technology, in the "big foam" foaming device to make appropriate adjustments and modifications, the production of a flat-top continuous foam (foam width of 2.2 m, foam height of 1.2 m) and foam density of about 14kg / m ~ 3 molded foam. The aerobic foam has a softer feel, higher open-cell structure and better elasticity than the larger foam.
