Umshini wokwenza isikhwama ngumshini wokwenza zonke izinhlobo zezikhwama zepulasitiki noma ezinye izikhwama ezibonakalayo. Uhla lwayo lokucubungula luyizinhlobo zonke zepulasitiki noma ezinye izikhwama ezibonakalayo ezinosayizi ohlukile, ubukhulu kanye nokucaciswa. Ngokuvamile, izikhwama zepulasitiki ziyimikhiqizo esemqoka.

I-2.SOPOROPITE yamapulasitiki

Ipulasitiki esivame ukuyisebenzisa akuyona into ehlanzekile. Yenziwe ngezinto eziningi. Phakathi kwazo, i-polymer ephakeme (noma i-sonthetic resin) yingxenye eyinhloko yamapulasitiki. Ngaphezu kwalokho, ukuze uthuthukise ukusebenza kwamapulasitiki, kuyadingeka ukwengeza izinto ezahlukahlukene zokusiza, ezinjengezilimi, amapulasitiki, ama-lubrifiants, ama-trastilics kanye namabala asebenza kahle.

1. Synthetic resin
I-Synthetic Resin iyingxenye esemqoka yamapulasitiki, futhi okuqukethwe kwawo kumapulasitiki ngokuvamile angama-40% ~ 100%. Ngenxa yokuqukethwe kwayo okuphezulu kanye nohlobo lwe-resin kuvame ukunquma uhlobo lwamapulasitiki, abantu bavame ukubheka kabusha njenge-synatics yamapulasitiki. Isibonelo, i-PVC Resin nePVC Plastic, Phenolic resin kanye neplastili ye-phenolic kudidekile. Eqinisweni, i-resin nepulasitiki yimibono emibili ehlukene. I-Resin iyi-polymer yokuqala engafakwanga. Akukasetshenziswa kuphela ukwenza amapulasitiki, kepha futhi kusetshenziswe njengento eluhlaza yezimbali, ukunamathela kanye nemicu yokwenziwa. Ngaphezu kwengxenye encane yamapulasitiki aqukethe ama-resin ayi-100%, iningi lamapulasitiki lidinga ukwengeza ezinye izinto ngokungezelela i-resin enkulu ye-resin.

2. Filler
Ama-Fillers, abizwa nangokuthi ama-filler, angathuthukisa amandla nokumelana nokushisa kwamapulasitiki futhi anciphise izindleko. Isibonelo, ukungezwa kwezinkuni powder to Phenolic resin kunganciphisa kakhulu izindleko, yenza iplastili yeplastili yeplosilic eyodwa yamapulasitiki ashibhile kakhulu, futhi athuthukise kakhulu amandla omshini. Ama-filler angahlukaniswa abe-organic filler kanye nabakwa-inorganic, okwedlule njengempuphu yezinkuni, ama-rags, iphepha kanye nemicu yendwangu ehlukahlukene, i-diatomite, asbestos, ikhabhoni emnyama, njll.

3. I-Plistic
Amapulasitiki angakhulisa ubukhulu beplastiki nokuthamba kwamapulasitiki, anciphise ubucwebe futhi enze ama-plastics kube lula ukucubungula futhi abumbele. Ama-Plasticizizers ngokuvamile abilayo ama-organic compounds angezingozi nge-resin, okungelona ubuthi, anobuthi futhi azinze ukukhanya nokushisa. Ama-Phthalates asetshenziswa kakhulu. Isibonelo, ekukhiqizweni kwamapulasitiki we-PVC, uma kungezwa amapulasitiki amaningi, iplastiki ye-PVC ethambile ingatholakala. Uma kungekho noma amapulasitiki angaphansi afakiwe (umthamo <10%), amapulasitiki e-PVC aqinile angatholakala.

Ukuze uvikele i-resin yokwenziwa kusuka ekubonweni futhi kulinyazwe ukukhanya nokushisa kwinqubo yokucubungula nokusebenzisa, futhi kwandiswe impilo yenkonzo, i-stabilizer kufanele ingezwe epulasitiki. Okuvame ukusetshenziswa kuyinto eqinile, i-epoxy resin, njll.

5. Umbala
Ama-Colorants angenza amapulasitiki abe nemibala ehlukahlukene ekhanyayo nenhle. Amadayi we-organic kanye nemibala engaphakathi kuvame ukusetshenziswa njengama-colors.

6. Ukugcotshwa
Umsebenzi wokugcotshwa ukuvikela ipulasitiki ukuthi unamathele isikhunta sensimbi ngesikhathi sokubumba, bese wenza ipulasitiki ebushelelezi futhi lihle. Izithambisi ezijwayelekile zifaka i-stearic acid kanye nosawoti wayo we-calcium magnesium.

Ngaphezu kwalokho izengezo ezingenhla, amalangabi ama-retaardants, ama-ejenti amagwebu kanye nama-antistatic agents angangezwa kumapulasitiki ahlangabezana nezidingo ezihlukile zohlelo lokusebenza.

Umshini wokwenza isikhwama se-Garment

Isikhwama se-Garment sibhekisele esikhwameni esenziwe ngefilimu ye-OPP noma i-PE, PP ne-CPP film, ngaphandle kwefilimu enamathela egumbini lokungena futhi livalwe ezinhlangothini zombili.

INJONGO:

Ngokuvamile sisetshenziselwa kakhulu ukupakisha izingubo zasehlobo, njengamahembe, iziketi, ibhulukwe, ama-buns, amathawula, isinkwa nezinkwa zobucwebecwebe. Imvamisa, lolu hlobo lwesikhwama luzifaka kuwe, olungabekwa uphawu ngqo ngemuva kokulayishwa kulo mkhiqizo. Emakethe yasekhaya, lolu hlobo lwesikhwama luthandwa kakhulu futhi luyasebenza kabanzi. Ngenxa yokubonakala kwayo okuhle, futhi kuyindlela efanelekile yokufaka izipho.
