Polypropylene (PP) shine resin thermoplastic mai ƙarancin yawa. Ana iya raba shi zuwa homopolypropylene (PP-H) da kuma copolymerized polypropylene. An ƙara raba polypropylene mai copolymerized zuwa tubali (mai jure tasirin) copolymerized polypropylene (PP-H). B) da kuma bazuwar (bazuwar) copolymerized polypropylene (PP-R). Akwai nau'ikan kayan PP da yawa, to menene bambance-bambancensu? A yau za mu koyi game da PP daban-daban tare da ku.
PP-H
An yi shi da polymer daga monomer guda ɗaya na propylene, shi ne mafi ƙarancin yawan robobi a cikin robobi na yau da kullun. Sarkar kwayoyin halittarsa tana da tsari sosai, don haka kayan yana da babban lu'ulu'u da kuma rashin tasirin tasiri.
Fa'idodi: ƙarfi mafi kyau da juriya ga tsatsa.
Rashin amfani: rashin juriya ga tasiri (ƙarancin ƙarfi), rashin ƙarfi, rashin daidaiton girma, sauƙin tsufa, rashin juriyar zafi da kwanciyar hankali na dogon lokaci, da kuma rashin kyawun kariya ga iskar oxygen, carbon dioxide da sauran iskar gas.
Amfani: Ana iya amfani da shi don shirya tef ɗin marufi, kwalaben da aka hura, goga, igiyoyi, jakunkunan saka, kayan wasa, manyan fayiloli, kayan lantarki, kayayyakin gida, akwatunan abincin rana na microwave, akwatunan ajiya, da kuma fina-finan takarda masu naɗewa.
Yadda ake gane: Idan wuta ta kone, wayar za ta yi lanƙwasa kuma ba ta da tsawo.
PP-B
Ana samunsa ta hanyar haɗa propylene da wani ɓangare na ethylene. Yawan sinadarin ethylene gabaɗaya yana tsakanin kashi 7 zuwa 15%. Duk da haka, saboda yuwuwar haɗa monomers guda biyu na ethylene da monomers guda uku a cikin PP-B yana da yawa sosai, yana nufin cewa monomer ɗin ethylene ya shiga cikin matakin sashi kawai, daidaiton PP-H ba ya raguwa, don haka ba za a iya cimma manufar inganta wurin narkewa ba, juriya ga matsin lamba na hydrostatic na dogon lokaci, juriya ga zafi na dogon lokaci da sarrafa bututu da kuma samar da kaddarorin PP-H ba.
Fa'idodi: ingantaccen juriya ga tasiri.
Rashin amfani: ƙarancin bayyanawa, ƙarancin sheƙi, ƙarancin juriya ga shan danshi, juriyar lalata acid da alkali, juriyar narkewa da juriyar iskar shaka a yanayin zafi mai yawa.
Amfani: Ana amfani da shi a cikin bumpers, kayayyakin sirara, kekunan motsa jiki, kayan wasanni, kaya, bokitin fenti, akwatunan batir, da kayayyakin sirara.
Yadda ake gane shi: Ba ya yin baƙi bayan an kunna shi kuma yana iya fitar da dogon waya mai zagaye.
PP-R
Ana samunsa ta hanyar haɗa propylene monomer da ƙaramin adadin ethylene (1-4%) monomer a ƙarƙashin tasirin zafi, matsin lamba da mai kara kuzari. Ana rarraba ethylene monomer bazuwar kuma bazuwar cikin dogon sarkar propylene. Ƙara ethylene bazuwar yana rage crystallinity da wurin narkewa na polymer, yana inganta tasirin kayan, juriya na dogon lokaci ga matsin lamba na hydrostatic, juriya na dogon lokaci ga tsufa na iskar oxygen da sarrafa bututu da ƙera shi.
Tsarin sarkar kwayoyin halitta na PP-R, abun da ke cikin ethylene monomer da sauran alamomi suna da tasiri kai tsaye kan kwanciyar hankali na dogon lokaci na zafi, halayen injiniya da aikin sarrafawa na kayan. Yayin da rarrabawar ethylene monomer a cikin sarkar kwayoyin halitta na propylene ke ƙaruwa, canjin halayen polypropylene zai fi muhimmanci.
Fa'idodi: kyakkyawan aiki gabaɗaya, ƙarfi mai yawa, juriya mai yawa, juriya mai kyau ga zafi, kwanciyar hankali mai kyau, ƙarfin ƙarancin zafin jiki mai kyau (sassauci mai kyau), bayyananne mai kyau, da kuma sheƙi mai kyau.
Rashin amfani: Mafi kyawun aiki tsakanin PP.
Amfani: Ana amfani da shi a cikin bututu, fina-finan rage kiba, kwalaben digo, kwantena masu haske sosai, kayayyakin gida masu haske, sirinji mai yarwa, da kuma fina-finan takarda masu marufi.
Yadda ake gane shi: Ba ya yin baƙi bayan an kunna shi kuma yana iya fitar da dogon waya mai zagaye.
