Sanda na PP (polypropylene) wani abu ne na Semi-crystalline wanda ya fito fili saboda haɗuwa ta musamman na kayan aikin jiki da na injiniya. Ɗaya daga cikin fitattun halayensa shine taurinsa da babban wurin narkewa, wanda ya bambanta shi da sauran kayan kamar PE (polyethylene). Yayin da nau'in homopolymer na PP zai iya zama mara ƙarfi lokacin da aka fallasa shi zuwa yanayin zafi sama da 0 ° C, yawancin kayan kasuwanci na PP ana ƙirƙira su azaman copolymers na bazuwar ko manne copolymers tare da bambance-bambancen kaso na ethylene.
Bazuwar copolymers yawanci sun ƙunshi 1 zuwa 4% ethylene, yayin da clamp copolymers suna da mafi girma rabo na ethylene. Wannan tsari na copolymerization yana haifar da wani abu na PP tare da ƙananan zafin jiki na murdiya (100 ° C) idan aka kwatanta da homopolymer PP. Kodayake nau'in nau'in copolymer PP abu na iya samun ƙaramin haske, mai sheki, da rigidity, yana nuna ƙarfin tasiri mai ƙarfi. Yayin da abun ciki na ethylene a cikin copolymer ke ƙaruwa, ƙarfin gabaɗayan kayan PP shima yana ƙaruwa, yana mai da shi zaɓi mai dacewa don aikace-aikace daban-daban.
Wani muhimmin sifa na PP shine zafin jiki na Vicat, wanda shine 150 ° C. Wannan tsayin daka na zafin jiki, haɗe tare da babban matakin kristal na kayan, yana haifar da kyawuwar ƙoshin ƙasa da juriya. Waɗannan kaddarorin suna sanya PP kyakkyawan zaɓi don aikace-aikace inda dorewa da juriya ga lalacewa da tsagewa ke da mahimmanci.
Bugu da ƙari kuma, PP an san shi da juriya ga matsalolin muhalli, wanda shine al'amari na kowa a cikin sauran kayan aiki. Wannan ya sa ya zama abin dogaron zaɓi don amfani a cikin mahalli inda mai yuwuwar bayyanar da sinadarai, danshi, ko wasu abubuwan damuwa.
Baya ga kaddarorin injin sa, PP kuma yana ba da kyakkyawan aiki. Ana iya siffata shi cikin sauƙi da ƙirƙirar ta ta amfani da hanyoyin masana'antu iri-iri, kamar gyare-gyaren allura, extrusion, da gyare-gyaren busa. Wannan juzu'i, haɗe tare da sauran kaddarorin sa, ya sa PP ya zama sanannen zaɓi don aikace-aikacen da yawa, gami da marufi, sassan mota, da samfuran mabukaci.
Gabaɗaya, sandar PP wani abu ne mai mahimmanci kuma mai ɗorewa wanda ke ba da haɗin kai na musamman na kayan aikin jiki da na injiniya. Matsayinsa na narkewa, kyakkyawan yanayin daɗaɗɗa da juriya, da juriya ga damuwa na muhalli ya sa ya zama kyakkyawan zaɓi don aikace-aikace masu yawa. Ko kuna neman wani abu wanda zai iya tsayayya da yanayin zafi, tsayayya da lalacewa, ko duka biyu, sandar PP shine abin dogara kuma mai amfani da zaɓi wanda ya tabbatar da biyan bukatun ku.
