Kugadzirwa kwepurasitiki

Plastiki - Izwi rinobva muchiGiriki (plastikos), rinoreva kuti rakakodzera kuumbwa, kureva, purasitiki mukugadzira, zvichivabvumira kukandwa.

Ita zvakasiyana-siyana zvemaumbirwo. Kugadzirwa kwepurasitiki kunogona kunzi inyanzvi yevanhu muzana ramakore rechi20, mushure memakore anopfuura zana ebudiriro, plastiki yave kwese kwese.

Paxsing

"Paksin" ndiyo yakatanga kuwanikwa - kukura kwepurasitiki. Mumakore ekuma1850, nyanzvi yemakemikari yeChirungu Parkes aitsvaga nzira dzekugadzira collodion,Netsaona yakasanganiswa collodion necamphor, ichigadzira. Chinhu chakaoma chinokwanisa kupeta. Uye akaritumidza kuti 'Paksin'. Kushandiswa kwepaki "Paxine" yakagadzira zvese kubva kumacombs kusvika kumabhatani kune zvishongo, uye vanhu vakazvida.

celluloid

Mumakore ekuma1860, Hiatt akavandudza nzira yekugadzira ye "Paksin" uye akaitumidza zita rokuti "Celluloid". "Ceruloc yakatanga kushandiswa mukugadzira mabhora emabhiriyoni, asi sezvo misika yepurasitiki yakaramba ichiwedzera, "Ceruloc" yakagadzirwa mumhando dzakasiyana-siyana.

Product. "Celluloid" ipurasitiki yakagadzirwa nevanhu, ine hunhu hunopisa moto, saka huwandu hwayo hwekugadzira zvigadzirwa hushoma.

Kugadzirwa kwe polyethylene

Muna 1933, Reginald Gibson naEric Fawcett veICI vakawana kuti ethylene inogona kuve polymerized mu polyethylene pasi pekumanikidzwa kwakanyanya.Iyi nzira yaizivikanwa senzira yepamusoro-soro, uye kugadzirwa kwemaindasitiri kwakatanga muna 1939. Polyethylene (PE) yakabva yashanduka kuita yakaderera-density. polyethylene (LDPE) uye yakakwirira-density polyethylene (HDPE) mumhando mbiri. Mukutanga kwema1950, American Phillips Oil Company yakawana chromium oxideSechinhu chinokonzera, ethylene inokwanisa kuita polymerized kugadzira polyethylene yakakwira-density pasi pekumanikidzwa kuri pakati nepakati, uye kugadzirwa kwemaindasitiri kwakaitika muna 1957. Mumakore ekuma60s, kambani yekuCanada yeDuPont yakatanga kushandisa ethylene uye a-Low density poly (B) munda wakagadzirwa kubva kuolefin nemhinduro nzira. PE yakachipa, inochinjika, yakasungirirwa uye inoshingirira kune makemikari corrosion. LDPE inoshandiswa mukugadzira mafirimu uye kurongedza zvinhu HDPE inonyanya kushandiswa kugadzira midziyo, pombi uye zvikamu zvemotokari.

Kambani yedu inoshandisa polyethylene zvigadzirwa

Zhongshang huangpu guoyu mapurasitiki ezvigadzirwa fekitori Bhizinesi guru rekupatsanura iindasitiri yepurasitiki, asi mukusarudza kwezvinhu zvichasarudza polyethylene, Chikonzero ndeye Polyethylene yayo isinganhuhwi, isina chepfu, inonzwa kunge wakisi, ine yakanakisa kuderera kwekushisa kwekudzivirira (kunyanya kushandiswa. tembiricha inogona kusvika -100 ~ -70 ° C), kugadzikana kwakanaka kwemakemikari, kuramba kune yakawanda acid uye alkali erosion (isingamiri kune asidhi ine oxidation zvinhu). Insoluble in general solvents at the room temperature, low water absorption, good magetsi ekudzivirira more serious. Japan inozvidza zvirambidzo zvepasirese pakuraswa kwemarara enyukireya, izvo zvinokuvadza nharaunda yezvakatipoteredza. Chatinogona kuita kuita nepatinogona napo kuchengetedza nharaunda yatinogona kurarama mairi
