Bhegi rakarukwa ibhegi repurasitiki rinowanzo shandiswa, rinonyanya kugadzirwa nepolyethylene kana polypropylene, rakatambanudzwa kuita sirika yakati sandara, yozorukwa, yakarukwa nekuiswa masaga.Nokuti simba, kuoma uye kujeka kwe polypropylene zviri nani kudarika polyethylene, saka inoshandiswa zvakanyanya, basa remabhegi akarukwa rinowedzerawo.Iwo anowanzo shandiswa semabhegi ekurongedza uye anogona kushandiswa kurongedza zvigadzirwa zvemaindasitiri uye zvekurima.Zvokudya, etc. Kunze kwezvo, kushanya.Mabhegi akarukwa anoshandiswawo mukurwisa mafashamo uye kubatsira panjodzi.
Bhegi rakarukwa, rinozivikanwawo sebhegi renyoka, imhando yebhegi repurasitiki, rinonyanya kushandiswa kurongedza, saka chii chinonzi bhegi repurasitiki rakarukwa?Kazhinji kutaura, mabhegi akarukwa ane maviri mbishi zvinhu:
1. Polyethylene
Iyo inozivikanwawo seP purasitiki ndeye thermoplastic resin yakagadzirwa ethylene polymerization.Polyethylene epurasitiki yakarukwa bhegi ine kuita kwakanaka, asi polyethylene inonzwa kushushikana kwezvakatipoteredza, kushomeka kwekupisa uye kuchembera, saka haishandiswe zvishoma muChina.
2. Polypropylene
Kazhinji kutaura, mabhegi mazhinji akarukwa muChina anogadzirwa ne polypropylene.Polypropylene (PP) is thermoplastic resin yakagadzirwa kubva kune acrylic polymer ine isotropic zvinhu.Random uye intergauge zvigadziriso zvitatu, simba rayo.Kuomarara uye pachena zviri nani pane polyethylene, uye inogona kugadziridzwa uye kuwedzera antioxidants kukunda yakaderera tembiricha kukanganisa kuramba, nyore kuchembera kukanganisa.
Muzvigadzirwa zvepurasitiki, mapurasitiki akarukwa imhando yezvinhu zvinochinjika zvine simba rekupwanya, izvo zvine chekuita nechimiro chayo chemolecular, crystallinity, dhizaini yedhizaini uye yekuwedzera mhando.Kana chirukwa chepurasitiki chikayerwa musimba chairo (simba/chaiyo giravhiti), yakakwirira kudarika kana pedyo nesimbi.
Patembiricha yemumba, jira rakarukwa repurasitiki rinonyatso shingirira kukukurwa kwemvura, uye mwero wekunyudzwa kwemvura uri pasi pe0 mukati memaawa makumi maviri nemana.01%.Kupinda kwemvura zvakare kwakadzikira.Pakutonhora kwakadzika, inova yakaoma.Mabhurukwa epurasitiki haakunde.
