Gulu la masika

Spring ikhoza kugawidwa m'magulu achilengedwe, opangira komanso opangira 3

(1) masika achilengedwe

kuchokera ku mphira wina wakale wokhotakhota molingana ndi zomwe zimaperekedwa ndi incision mu nthawi yomwe madzi amatuluka, ali ndi mkaka-woyera, olimba ndi 30% ~ 40%, pafupifupi mphira wa tinthu tating'onoting'ono ta 1. 6 microns. Kasupe watsopano wachilengedwe wokhala ndi mphira 27% ~ 41. 3% (Quality) 0, 44% ~ 70% madzi, mapuloteni. 2% ~ 4. 0, utomoni wachilengedwe 2% ~ 5%, shuga 5%. 36% ~ 4. 2%, phulusa 0. 4%. Pofuna kupewa masoka kasupe chifukwa cha zochita za tizilombo, michere ndi solidification, nthawi zambiri agwirizane ammonia ndi stabilizer zina. Natural kasupe zimagwiritsa ntchito kupanga siponji mankhwala, extruded mankhwala ndi impregnated mankhwala.

(2) kaphatikizidwe ka masika

opangidwa ndi emulsion polymerization, monga polybutadiene kasupe, butyl benzene masika. Kuti olimba zili 40% ~ 70%, choyamba kupanga mphira particles agglomeration mu zikuluzikulu particles, kutengera njira yofanana zachilengedwe kasupe kulemerera. Kuphatikizika kwa masika kumagwiritsidwa ntchito kwambiri popanga makapeti, kupanga mapepala, nsalu, kusindikiza, zokutira ndi zomatira.

3. Masika Opanga

ndi mtundu wa emulsion polymerization wa mphira masika. Kuwonjezera madzi ndi colloid kwaiye njira polymerization surfactant, kupanga mphira particles omwazikana m'madzi, ndiyeno steamed kuwonjezera pa zosungunulira. Ngati mphira si mokwanira kusungunuka mu zosungunulira, yaiwisi mphira ndi mphira akhoza kukhala pamaso pa amadzimadzi gawo munali emulsifier, kusinja, mpaka ena mawonekedwe khola mphira. Cholinga cha kasupe wochita kupanga ndi kasupe wopangira ndizofanana
