1. PVC: Zita remakemikari ari Polyvinyl chloride, iro rakakamurwa kuRigid polyvinyl chloride uye nyoro polyvinyl chloride. Simba rakakwirira simba, zvemo zvemakemikari vinyl chloride (codened pvc) is a synthetic polymer yakaumbwa ne polymerization ye vinyl chloride monomer. Polyvinyl chloride ndeye chena kana mwenje yero yero powdery resin nehuremu hwe1,4 uye chlorine yezvinyorwa zve56% kusvika 58%. Kuwedzera akasiyana mapurasitiki uye stabilizers kune iyo polyvinyl chloride resin inogona kuburitsa yakasiyana yakaoma polyvinyl chloride uye yakapfava polyvinyl chloride.
Polyvinyl chloride pachayo inzvimbo yemutsara, nekuti simba rinokwezva pakati pemamolekyu yakasimba kwazvo, uye dzakasimba uye dzakasungirirwa kune mumwe nemumwe, kuti polymer keteni isingafarire, saka chimiro chakaoma. Kana iyo resin isingawedzerwe kana kuwedzerwa (isingasviki 10%) Plasticzezer, mhedzisiro yacho yakaoma polyvinyl chloride. Tigid Polyvinyl Chloride ane dentity yakakwirira, acid kupokana, Alkali kuramba uye kudzivisa kupokana, saka zvinowanzoshandiswa se pombi dzemidziyo yemakemikari uye mapuranga ekuvaka, senge marara nemakuva.
Kana mamwe mapurasitiki anowedzerwa kune iyo resin, yakapfava polyvinyl chloride inogona kuwanikwa. Iyo yakawanda mapurasitiki inowedzerwa, iyo inopinduka iyo mapurasitiki. Nyoro Polyvinyl Chloride is elastic, inodzivirira kupeta, mwenje, mvura, uye oxidation, saka inowanzoitwa kugadzira mafirimu uye waya mapepa ekuputira uye waya mapepa ekuputira uye waya mapepa ekuputira. Polyvinyl chloride zvigadzirwa muhupenyu hwezuva nezuva hupenyu hwakanyanya kupfava polyvinyl chloride. Semuenzaniso, dehwe rekugadzira rakagadzirwa nePVC rakashandiswa zvakanyanya muzvipfeko, shangu, masutukesi, uye mabhegi ematehwe.
Kana mumiriri anopumha achiwedzerwa kuPolyvinyl chloride plastics, dzakasarudzika mapurasitiki dzinogona kugadzirwa. Iyo ine zvinhu zvakanaka kwazvo sehuremu hwakareba, kupisa kwekusimbisa, kurira kwekunzwa, etc., uye kunoshandiswa zvakanyanya mumaindasitiri sekutuka, zvekuvakisa, kugadzira kwendege uye kugadzira kwendege.
2. Nylon Polyamide inowanzozivikanwa sePolyamide (PA ye pfupi) muChirungu. Iro izwi rakawanda rekuti Thermplastic resins rine kudzokorora mapoka mapoka- [nhco] -Pa] -Pa] - iyo mainini main mony ye molecule. Inosanganisira aliphatic pa, aliphatic-anomatic pa nekunhuhwirira pa. Pakati pavo, Aliphatic Pa ane marudzi mazhinji, akakura uye anoshanda akashanda, uye zita rayo rinotemwa neiyo nhamba yekaroni yeiyo menomer.
The main varieties of nylon are nylon 6 and nylon 66, occupying an absolute dominant position, followed by nylon 11, nylon 12, nylon 610, nylon 612, in addition to nylon 1010, nylon 46, nylon 7, nylon 9, nylon 13, Nyowani pane nylon 6i, nylon 9T uye Special NYLONI MENYON, SEINFECATION SHON (MC NYLON), Rim) Nylon, uye Anonatsan nylon, pachena nylon, yakanyanya kukanganisa (Super yakaoma) nylon, kuitisa nylon, etc. sesimbi uye huni zvekushandisa, seyakasiyana-siyana mamiriro.
Nylon ndiyo inonyanya kukosha engineering mapurasitiki, uye yayo inobuda inotanga pakati pemapurasitiki mashanu echienda.
Zvivakwa zve nylon:
Nylon fungidziro yekunetseka trublent kana Milky White Crystalline Resin. Iyo smecular uremu hwenylon sapurasitiki yeinjiniya inowanzoitika zviuru gumi nezvishanu kusvika makumi matatu. Nylon ine simba rakanyanya simba, kupfupikisa kupokana, kupokana kuderera, kupokana nekudzikisira, kushaya simba kupokana, kusimba kweiyo sol. -Kutenda, kusiri-chine chepfu, kusanzwisisika, kwakanaka kudzvinyirira mamiriro ekunze, kushaya mhosva. Iko kushushikana ndeyekuti iyo mvura yekukanda yakakura, iyo inokanganisa kugadzikana kwemukati uye zvivakwa zvemagetsi. Fiber kusimbiswa kunogona kuderedza iyo yemvura yekubatidza kwemvura yeiyo resin, kuitira kuti inogona kushanda pasi pekupisa kwakanyanya uye kunyorova kwakanyanya. Nylon ine yakanyanya kunaka kubatana negirazi fiber. Zvinowanzoshandiswa kuita ma coms, mazino, zvipfeko zvikorekedzo, maFanana, net bhegi tambo, mabhegi ekunze ekutakura mabhegi uye zvichingodaro. Isiri-ine chepfu, asi kwete kusangana kwenguva refu neAcid naAlkali.
Zvakakosha kucherechedza kuti mushure mekuwedzera girazi fiber, simba renzvimbo yeNylon rinogona kuwedzerwa neinenge 2 times, uye kugona kuramba kuramba kwakavandudzwa zvakare.
Iyo shrinkage rate of nylon ndeye 1% ~ 2%
