Uke waqaphela unxantathu ngaphansi kwesitsha sepulasitiki?Zimeleni izinombolo ezihlukene kunxantathu?I-LGLPAK.LTD izokuyisa ukuthi uqonde ukuthi izinombolo zimeleni.
Kunezinombolo ezingu-1-7 kunxantathu phansi kwesitsha sepulasitiki, ezimele izinto ezihlukahlukene zepulasitiki, futhi lawa makhodi wezinto zepulasitiki ayisisekelo esibalulekile sokuphepha kwawo.
1-PET PET ibhodlela
Yenziwe nge-polyethylene terephthalate, engeyona enobuthi, inomoya omuhle wokuqina, futhi ayikhiqizi ama-flocs.Ngemuva kokuvuselelwa, kuba yinto yesibili enezinzuzo zezomnotho, ngoba ukusetshenziswa kwayo kukhula kakhulu., Izinto zesibili zinikezwa ekhaya naphesheya, futhi zithunyelwa ezweni laseChina, ezingasetshenziswa njengezintambo ezingezona ezilukiweyo, iziphuphu, izinto zokugcwalisa, njll.
2-HDPE high density polyethylene
Impushana emhlophe noma umkhiqizo oyimbudumbudu, ongenabuthi futhi awunambitheki, icrystallinity ingu-80%～90%, indawo yokuthambisa ingu-125℃ 35℃, izinga lokushisa lesevisi lingafinyelela ku-100℃, amandla aphindwe kabili kunawe-polyethylene ephansi, isikhwama sepulasitiki Izinto ezivamile.
3-PVC polyvinyl chloride
Njengamanje ingumkhiqizo wepulasitiki wesibili ngobukhulu emhlabeni ngemuva kwe-polyethylene.Inokwakheka kwe-amorphous yempushana emhlophe, enezinga elincane le-branching, ukuminyana okuhlobene okungaba ngu-1.4, izinga lokushisa lokushintsha kwengilazi elingu-77 ~ 90 ° C, nokubola cishe ku-170 ° C.Inokungaqini kahle kokushisa futhi iyabola ukuze ikhiqize i-hydrogen chloride emazingeni okushisa angaphezu kuka-100°C noma ekukhanyeni kwelanga isikhathi eside.
I-4-LDPE i-polyethylene enezinga eliphansi
Iwuhlobo olusetshenziswa kakhulu embonini yokupakisha nokuphrinta yepulasitiki emazweni ahlukahlukene.Icutshungulwa ibe yifilimu ye-tubular ngendlela yokubumba i-blow futhi ifanele ukupakishwa kokudla, ukupakishwa kwamakhemikhali kwansuku zonke, ukupakishwa komkhiqizo we-fiber, njll. Izinto ezibonakalayo azikwazi ukumelana nokushisa futhi zizoncibilika lapho izinga lokushisa lidlula u-110 ° C.Uma ukudla kusongwe ngepulasitiki futhi kushisiswe, kuzoncibilikisa izinto eziyingozi.
5-PP polypropylene
Amandla ayo okusebenza, amandla okugoqa, ukuminyana komoya, kanye nokuvimbela umswakama kungcono kunefilimu yepulasitiki evamile.Ngenxa yokuthi le filimu yepulasitiki inokukhanyela okuhle kakhulu, umbala owenziwe kabusha ngemva kokuphrinta ukhanya ngokwedlulele futhi muhle, futhi uyinto ebalulekile yokupakisha okuyinhlanganisela yepulasitiki evumelana nezimo.Imelana nokugqwala ngama-asidi, ama-alkali, izixazululo zikasawoti kanye nezinhlobonhlobo zezinyibilikisi eziphilayo ezingaphansi kuka-80℃, futhi ingabola ngaphansi kwezinga lokushisa eliphezulu kanye ne-oxidation.
I-6-PS i-polystyrene
Izinto ezisetshenziselwa ukwenza amabhokisi ama-noodle asheshayo kusihlwa namabhokisi okudla okusheshayo zinokumelana nokushisa okuhle, kodwa azikwazi ukufakwa kuhhavini we-microwave.Izinga lokushisa eliphezulu lizokhipha amakhemikhali anobuthi.Ama-asidi aqinile nama-alkali nawo angabola i-polystyrene eyingozi emzimbeni womuntu.Qaphela lapho uyisebenzisa.
7-PC polycarbonate nabanye
I-PC iyinto esetshenziswa kakhulu, esetshenziswa kakhulu ekwenzeni amabhodlela ezingane, izinkomishi zasemkhathini, njll. Kuyimpikiswano ngenxa yobukhona be-bisphenol A. Ukuphakama kwezinga lokushisa, kukhulu ukukhululwa, kanye nesivinini esisheshayo.Ngakho-ke, ungasebenzisi ibhodlela le-PC ukuze ubambe amanzi ashisayo futhi ungawavezi elangeni eliqondile.
Ngicabanga ukuthi wonke umuntu useyayiqonda incazelo yezinombolo.Ungakwazi ukunaka kakhulu empilweni yakho futhi uzame ukugwema izinto eziyingozi emzimbeni wakho.I-LGLPAK.LTD izokuyisa ukuthi uqonde imboni yepulasitiki ngokombono wochwepheshe.
