Isidingo sokudla okulula, okulungele ukudliwa besilokhu sikhula eminyakeni yamuva nje. Ngenxa yalokho, ukupakishwa kokudla kudlala indima ebalulekile ekuqinisekiseni ukuthi lokhu kudla kuphephile, kusha, futhi kuyakhanga. Faka i- CPET amathreyi , isisombululo sokupakisha esisha esiguqula imboni yokudla okulungele.

Isingeniso ku- Amathreyi okudla e-CPET CPET amathreyi , noma i-Crystallized Polyethylene Terephthalate amathreyi , iyisisombululo esisha sokupakisha ukudla. Sezithandwa kakhulu ngenxa yokuguquguquka kwazo, ukuqina, kanye nokusimama. Kulesi sihloko, sizongena ezweni le- CPET amathreyi futhi sihlole

Ezweni lanamuhla elisheshayo, ukulula kanye nokuguquguquka kubalulekile ekupakisheni umkhiqizo. Enye yezinto eziye zathandwa kakhulu ngenxa yezinzuzo zayo eziningi yi CPET (Crystalline Polyethylene Terephthalate). Kulesi sihloko, sizoxoxa nge CPET amathreyi kanye nokusetshenziswa kwazo okuhlukahlukene, izinzuzo, kanye nezimboni.

PET isifinyezo se-polyethylene terephthalate yesiNgisi. Kusho amapulasitiki e-polyethylene terephthalate, ikakhulukazi afaka phakathi i-polyethylene terephthalate PET kanye ne-polybutylene terephthalate PBT. I-polyethylene terephthalate yaziwa nangokuthi i-polyester resin. Isakhiwo sepulasitiki se- PET I-str yama-molecule

Uyini umehluko phakathi kokuphrinta kwe-offset nokuphrinta kwedijithali? Ukuphrinta kwe-offset kukhiqizwa kuphrinta kusetshenziswa amapuleti okuphrinta kanye noyinki omanzi. Lolu hlobo lokuphrinta luthatha isikhathi eside ukukhiqizwa ngoba kunesikhathi esengeziwe sokusetha futhi umkhiqizo wokugcina kumele womiswe ngaphambi kokuqeda. Ngesikhathi esifanayo, o

I CPET iyinto enobungani nemvelo eyenziwe nge-polyethylene terephthalate, engenaphunga, engenambala, ebolayo, futhi engenabuthi. CPET impahla ibhekwa njengezinto zokupakisha ukudla ezinhle kakhulu emhlabeni namuhla. CPET impahla idlula ezinqubweni ezithile zokukhiqiza ezikhethekile - I-Blister pr

Iyini ngempela impahla yepulasitiki PVC ? PVC , igama eligcwele yi-Polyvinylchloride, ingxenye eyinhloko yi-polyvinyl chloride, kanti ezinye izingxenye zengezwa ukuze kuthuthukiswe ukumelana kwayo nokushisa, ukuqina, ukuguquguquka, njll. Izendlalelo ezintathu ze PVC impahla yeshidi Ingqimba ephezulu ye PVC yi-lacquer, ingxenye eyinhloko ephakathi nendawo.

Njengengxenye ebalulekile yefomula yemikhiqizo eguquguqukayo PVC , i-plasticizer inethonya elikhulu ekusebenzeni kwemikhiqizo eguquguqukayo PVC . Uma imikhiqizo ethambile ye- PVC PVC (amakhethini omnyango wokugcina abandayo) kudingeka ukuthi isetshenziswe emazingeni okushisa aphansi, ama-plasticizer anokumelana okuhle nokushisa kumele akhethwe.

Ibhodi le-foam PVC liyizinto ezintsha zepulasitiki ezilula, ezine- PVC njengezinto eziyinhloko zokusetshenziswa. Ibhodi le-foam PVC lenziwa ngezinqubo ezikhethekile zokukhipha amagwebu, njenge-foam yamahhala noma i-celuka. Ibhodi le-foam PVC alinawo umswakama, liyamelana nokuzicisha, aliguquguquki, alinabo ubuthi, futhi liyakwazi ukulwa nokuguga. Okwamanje, linayo i-e

I-DOP ne-DOTP ziyizinto zokwenziwa kwepulasitiki ezisetshenziswa kabanzi ezisetshenziselwa ukwenza PVC ibe mnene, iguquguquke futhi kube lula ukuyicubungula. Umehluko omkhulu isakhiwo sazo sama-molecule: I-DOP, evame ukubhekisela ku-DEHP, iyi-orthophthalate, kuyilapho i-DOTP, ebizwa nangokuthi i-DEHT, iyi-terephthalate futhi ivame ukukhethwa njengenye indlela engeyona i-orthophthalate.

Izinhlobo eziningi zezinto zepulasitiki ziyatholakala embonini yokupakisha. Uma udinga ukupakisha imikhiqizo yakho, ungathola maduze izinto ezimbili zepulasitiki ezisetshenziswa kakhulu: PET kanye nezinto zepulasitiki PVC KwaHuisuqinye Plastics Group, amakhasimende avame ukusibuza ukuthi yiziphi izinto zepulasitiki eziye zabonakala ziyi-
