Ammonium polyphosphate inoshanda sei muPolypropylene(PP)?
Polypropylene (PP) chinhu chinoshandiswa zvakanyanya muthermoplastic, chinozivikanwa nehunyanzvi hwayo hwakanaka hwemakanika, kuramba makemikari, uye kuramba kupisa. Zvisinei, PP inogona kutsva, izvo zvinoderedza kushandiswa kwayo mune dzimwe nzvimbo. Kugadzirisa dambudziko iri, kushandiswa kweammonium polyphosphate (APP) sechinhu chinodzivirira moto muPP kwakadzidzwa zvakanyanya.
Ammonium polyphosphate, rudzi rwemuto unodzivirira moto, inowedzerwa kuPP kuti iwedzere kudzivirira moto. Kana PP ine APP ikasangana nekupisa kwakanyanya panguva yemoto, ammonium polyphosphate inoora yoburitsa ammonia, iyo inoderedza huwandu hwemagasi anobvira anogadzirwa panguva yemoto. Maitiro aya anoderedza mukana wekubvira uye anononoka kupararira kwemoto.
Uyezve, kugona kweammonium polyphosphate kugadzira char kunobatsira kugadzira char layer yakasimba uye inodzivirira pamusoro pePP kana yaiswa pamoto kana murazvo. Char layer iyi inoshanda sechidziviriro, ichidzivirira PP iri pasi pamoto uye ichideredza kuburitswa kwemagasi anobvira moto, nokudaro ichivandudza hunhu hwePP hunodzivirira moto.
Muchidimbu, kuwedzerwa kweammonium polyphosphate kuPP hakungoderedzi kupisa kwechinhu ichi nekudurura magasi anobvira asi kunokurudzirawo kuumbwa kwechar layer inodzivirira, nokudaro zvichivandudza kudzivirira kupisa kwepurasitiki yePP. Izvi zvinoita kuti PP ine ammonium polyphosphate ive sarudzo inodiwa yekushandisa uko kuchengetedzeka kwemoto kuri kwakakosha zvikuru.
