[Nau'in jakunkuna da aka saka]

Samar da ƙasashen waje galibi polyethylene (PE), samarwa na cikin gida galibi polypropylene (PP), wani nau'in guduro ne na thermoplastic wanda ethylene polymerization ke samarwa. A masana'antu, shi ma ya haɗa da copolymers na ethylene tare da ƙananan adadin -olefin. Polyethylene wari, ba mai guba, jin kamar kakin zuma, yana da kyakkyawan juriya mai ƙarancin zafin jiki (mafi ƙarancin amfani da zafin jiki zai iya zuwa -70 ~ -100 ℃), kwanciyar hankali mai kyau na sinadarai, zai iya jure wa yawancin acid da yashwar alkali (babu oxidation na acid), yanayin zafin jiki wanda ba zai iya narkewa a cikin kaushi na gabaɗaya, ƙananan shayar ruwa, kyakkyawan aikin haɓakar lantarki; Amma polyethylene yana kula da matsalolin muhalli (sakamakon sunadarai da na inji) kuma yana da ƙarancin juriya ga tsufa na thermal. Abubuwan da ke cikin polyethylene sun bambanta daga nau'in nau'in zuwa nau'in, galibi ya danganta da tsarin kwayoyin halitta da yawa. Ana iya samun samfuran da yawa daban-daban (0.91 ~ 0.96g / cm3) ta amfani da hanyoyin samarwa daban-daban. Ana iya sarrafa polyethylene ta hanyar gyare-gyaren thermoplastic gabaɗaya (duba sarrafa filastik). Ana amfani da shi sosai a cikin masana'antar fim, akwati, bututu, waya guda ɗaya, waya da kebul, bukatu na yau da kullun, da dai sauransu, kuma ana iya amfani da shi azaman kayan haɓaka mai ƙarfi don TV, radar, da sauransu. A cikin 1983, yawan ƙarfin samar da polyethylene ya kasance 24.65Mt, kuma ƙarfin shukar da ake ginawa shine 3.16Mt.

Polypropylene (PP)

Gudun thermoplastic wanda aka shirya ta hanyar polymerization na propylene. Akwai jeri guda uku na samfuran isochronous, marasa tsari da samfuran tsaka-tsaki, kuma samfuran isochronous sune manyan abubuwan samfuran masana'antu. Polypropylene kuma ya haɗa da copolymers na propylene da ƙaramin adadin ethylene. Yawancin lokaci mai ƙarfi mara launi mara launi, mara wari mara guba. Saboda tsarin ne m kuma sosai crystallized, don haka narkewa batu har zuwa 167 ℃, zafi juriya, kayayyakin za a iya amfani da tururi disinfection ne ta fice abũbuwan amfãni. Tare da yawa na 0.90g/cm3, shine filastik mafi sauƙi na duniya. Rashin juriya, ƙarfin 30MPa, ƙarfin ƙarfi, tsauri da nuna gaskiya sun fi polyethylene kyau. Rashin lahani shine juriya mai ƙarancin zafin jiki da sauƙin tsufa, wanda za'a iya shawo kan shi ta hanyar gyare-gyare da ƙari na antioxidant bi da bi.

Launin jakar da aka saƙa gabaɗaya fari ce ko launin toka, ba mai guba da ɗanɗano ba, gabaɗaya ba ta da lahani ga jikin ɗan adam, duk da cewa an yi ta da robobin sinadarai iri-iri, amma kare muhalli ya fi ƙarfi, ƙarfin sake yin amfani da shi ya fi girma;
