Nau'in jakunkuna da aka saka

Ana kuma kiran buhunan saƙa da buhunan maciji. Wani nau'in filastik ne, galibi ana amfani da shi don marufi. Kayan albarkatun kasa gabaɗaya shine polyethylene, polypropylene da sauran kayan albarkatun filastik sinadarai. Anan ga taƙaitaccen gabatarwar nau'in jakar saƙa da amfani.

Polyethylene shine babban albarkatun kasa na samar da waje, polypropylene shine babban samfurin gida. Guduro ne na thermoplastic wanda aka yi ta hanyar polymerization na ethylene. A cikin masana'antu, kuma ya haɗa da copolymers na ethylene tare da ƙaramin adadin α-olefin. Polyethylene ba shi da wari, ba mai guba ba, waxy, yana da kyakkyawan juriya mai ƙananan zafin jiki (mafi ƙarancin aiki har zuwa -70 ~ -100 ℃), kwanciyar hankali mai kyau na sinadaran, yawancin acid da alkali juriya (juriya na acid, hadawan abu da iskar shaka), insoluble a general solvents a dakin da zazzabi, low ruwa sha, m lantarki rufi yi; Duk da haka, polyethylene yana da matukar damuwa ga matsalolin muhalli (sakamakon sunadarai da na inji) kuma yana da mummunan juriya ga tsufa. Abubuwan da ke cikin polyethylene sun bambanta daga iri-iri zuwa iri-iri, galibi dangane da tsarin kwayoyin halitta da yawa. Hanyoyin samarwa daban-daban na iya haifar da yawa daban-daban (0.91-0.96g/cm3). Ana iya sarrafa polyethylene kamar yadda ake ƙera robobi na thermoplastic na yau da kullun (duba sarrafa Filastik). An yi amfani da shi sosai wajen samar da fina-finai, kwantena, bututu, waya guda ɗaya, waya da kebul, bukatu na yau da kullun, da dai sauransu Ana iya amfani da shi azaman babban abin rufewa don TV, radar, da sauransu. A shekarar 1983, jimilar samar da polyethylene a duniya ya kai metric ton 24.65, kuma injin da ake ginawa yana da karfin metric ton 3.16.

Polypropylene (PP)

Gudun thermoplastic da aka yi ta hanyar polymerization na propylene. Akwai nau'ikan jeri guda uku, wato, cikakken isotopic, atactic da kuma kaikaice. Kayayyakin masana'antu galibi sun ƙunshi sifofin isotopic. Polypropylene kuma ya haɗa da copolymer na propylene da ƙaramin adadin ethylene. Yawancin lokaci yana da ƙarfi, mara launi, mara wari kuma mara guba. Saboda tsarin tsarinsa, babban crystallinity, ma'ana mai narkewa har zuwa 167 ℃, juriya mai zafi. Tare da yawa na 0.90g/cm3, shine filastik mafi sauƙi. Rashin juriya, ƙarfin 30MPa, ƙarfin ƙarfi, tsauri da nuna gaskiya sun fi polyethylene kyau. Rashin hasara shine juriya mai ƙarancin zafin jiki mara kyau, mai sauƙin tsufa, amma ana iya gyaggyarawa da ƙara antioxidant don cin nasara.

Launin jakar da aka saƙa fari ne ko fari-fari gabaɗaya, ba mai guba da ɗanɗano ba, cutar da jikin ɗan adam gabaɗaya ya fi ƙanƙanta. Ko da yake an yi shi da nau'ikan robobi na sinadarai, amma ƙaƙƙarfan kariyar muhalli, ƙarfin sake yin amfani da su;

Ana amfani da jakar da aka saka a ko'ina, galibi ana amfani da su don tattara kayayyaki iri-iri, kuma ana amfani da su sosai a masana'antu;

Filastik saƙa jakar da polypropylene guduro a matsayin babban albarkatun kasa, extrusion da kuma shimfiɗa a cikin lebur zaren, sa'an nan saka a cikin jaka.

Haɗaɗɗen jakar saƙa na filastik tare da zanen filastik azaman kayan tushe, ta hanyar gyare-gyaren kwarara.

Ana amfani da shi don shirya foda ko ƙwanƙwaran kayan granular da labarai masu sassauƙa. An raba jakar da aka saƙa na filastik zuwa biyu a cikin jaka ɗaya da uku a cikin jaka ɗaya bisa ga babban abun da ke ciki.

Dangane da hanyar dinki, ana iya raba shi zuwa jakar dinki na kasa, jakar kasa ta gefe, jakar sakawa da jakar dinki mai dinki.

Dangane da nisa mai tasiri na jakar, ana iya raba shi zuwa 450, 500, 550, 600, 650 da 700 mm. Ƙungiyoyin biyu za su amince da ƙayyadaddun bayanai na musamman.
