PETG ipurasitiki yakagadziridzwa yePET. Iyo ipurasitiki yakajeka, isina-crystalline copolyester, PETG inowanzoshandiswa comonomer ndeye 1,4-cyclohexanedimethanol (CHDM), zita rakazara ndiro polyethylene terephthalate-1,4-cyclohexanedimethanol. Kuenzaniswa nePET, kune mamwe 1,4-cyclohexanedimethanol comonomers, uye kana ichienzaniswa nePCT, kune akawanda ethylene glycol comonomers. Naizvozvo, kuita kwePETG kwakasiyana kwazvo neiyo yePET uye PCT. Zvigadzirwa zvaro zvinoonekera zvakanyanya uye zvine hunyanzvi hwekupikisa, kunyanya zvakakodzera kugadzira zvigadzirwa zvakakora-walled zvinoonekera.
Sechinhu chekurongedza,PETGine zvinotevera zvakanakira:
1. Kujeka kwepamusoro, kutenderera kwechiedza kusvika ku90%, kunogona kusvika pakujeka kweplexiglass;
2. Iine kuomarara kwakasimba uye kuoma, yakanakisa kukwenya kuramba, kukanganisa kupikisa uye kuoma;
3. Panyaya yekupikisa kwemakemikari, mafuta ekudzivirira, kupikisa kwemamiriro ekunze (yellowing) kushanda, simba remagetsi, uye chipingamupinyi chekuita kune oksijeni uye mhute yemvura, PETG iri naniwo kupfuura PET;
4. Isiri-chepfu, yakavimbika yehutsanana kuita, inogona kushandiswa pakudya, mushonga uye kumwe kurongedza, uye inogona kuomeswa ne gamma mwaranzi;
5. Inosangana nezvinodiwa zvekuchengetedzwa kwezvakatipoteredza uye inogona kushandiswa zvakare mune zvehupfumi uye zviri nyore. Apo tsvina inopiswa, hapana zvinhu zvinokuvadza zvinoisa mungozi mhoteredzo zvichagadzirwa.
Sechinhu chekurongedza,PETine zvinotevera zvakanakira:
1. Iine maitiro akanaka emagetsi, simba rinokonzera 3 ~ 5 nguva yemamwe mafirimu, kupeta kwakanaka kupikisa, uye kuchiri nekuoma kwakanaka pa -30 ° C;
2. Inopikisa mafuta, mafuta, dilute acid, dilute alkali, uye zvakawanda zvinonyungudutsa;
3. Yakaderera gasi uye mvura mhute permeability, yakanakisa gasi, mvura, mafuta uye kunhuwa kuramba;
4. Isiri-chepfu, isina kunaka, yehutsanana uye yakachengeteka, inogona kushandiswa zvakananga mukurongedza chikafu;
5. Mutengo wezvinhu zvakasvibirira unodhura kudarika PETG, uye chigadzirwa chakapedzwa chakareruka muhuremu uye chinopesana nekuputsika, izvo zviri nyore kune vanogadzira kuderedza kugadzirwa uye mari yekufambisa, uye kushandiswa kwemari kwese kwakakwirira.
PETG yakakwirira kune yakajairwa PET munzvimbo dzepamusoro senge kudhinda uye kunamatira. PETG pachena inofananidzwa PMMA. Iko kuoma, kutsvedza, uye post-kugadziridza kugona kwePETG kwakasimba kupfuura PET. Kuenzaniswa nePET, kukanganisa kwePCTG kuri pachena zvakare, ndiko kuti, mutengo wakakwirira kwazvo, iyo 2 ~ 3 nguva yePET. Parizvino, mazhinji emabhodhoro ekurongedza zvinhu pamusika anonyanya PET zvinhu. PET zvinhu zvine hunhu hwehuremu huremu, kujeka kwepamusoro, kupokana kwemhedzisiro uye kwete kutetepa.
Pfupiso: PETG ishanduro yakakwidziridzwa yePET, ine kujeka kwepamusoro, kusimba kwepamusoro, kuramba kuri nani, uye zvechokwadi mutengo wepamusoro.
