Chilichonse chomwe chingathe kukonza zoyambira za utomoni kudzera muzochita zakuthupi, zamakina ndi zamankhwala zitha kutchedwakusintha kwa pulasitiki.Tanthauzo la kusinthidwa kwa pulasitiki ndi lalikulu kwambiri.Panthawi yosinthidwa, kusintha kwa thupi ndi mankhwala kungathe kukwaniritsa.

Njira zomwe zimagwiritsidwa ntchito kwambiri posinthira pulasitiki ndi izi:

1. Onjezani zinthu zosinthidwa

a.Onjezani mamolekyu ang'onoang'ono osakhazikika kapena organic

Zowonjezera zowonjezera monga ma fillers, reinforcing agents, retardants lawi, colorants ndi nucleating agents, etc.

Zowonjezera organic kuphatikizapo plasticizers, organotin stabilizers, antioxidants ndi organic flame retardants, Degradation additives, etc. Mwachitsanzo, Topfeel amawonjezera zowonjezera zowonongeka m'mabotolo ena a PET kuti apititse patsogolo kuwonongeka ndi kuwonongeka kwa mapulasitiki.

b.Kuwonjezera zinthu za polima

2. Kusintha kwa mawonekedwe ndi mawonekedwe

Njirayi imayang'ana kwambiri kusintha mawonekedwe a utomoni ndi kapangidwe ka pulasitiki palokha.Njira yachizolowezi ndikusintha mawonekedwe a kristalo apulasitiki, crosslinking, copolymerization, kulumikiza ndi zina zotero.Mwachitsanzo, styrene-butadiene kumezanitsa copolymer bwino zotsatira za PS chuma.PS imagwiritsidwa ntchito kwambiri m'nyumba za ma TV, zida zamagetsi, zolembera zolembera, zoyikapo nyali ndi mafiriji, ndi zina.

3. Kusintha kwamagulu

Kusintha kwamagulu a pulasitiki ndi njira yomwe zigawo ziwiri kapena zingapo za mafilimu, mapepala ndi zipangizo zina zimaphatikizidwa pamodzi pogwiritsa ntchito zomatira kapena kutentha kusungunuka kuti apange filimu yamitundu yambiri, mapepala ndi zipangizo zina. pulasitiki zodzikongoletsera machubu ndimachubu a aluminiyamu-pulasitikiamagwiritsidwa ntchito mu nkhani iyi.

4. Kusintha pamwamba

Cholinga cha kusinthidwa kwa pulasitiki kungathe kugawidwa m'magulu awiri: imodzi imasinthidwa mwachindunji, ina imasinthidwa mosadziwika bwino.

a.Kusinthidwa mwachindunji kwa pulasitiki kuphatikizira gloss, kuuma kwapamtunda, kukana kuvala pamwamba ndi kukangana, anti-kukalamba pamwamba, retardant yamoto yamoto, ma conductivity a pamwamba ndi zotchinga pamwamba, etc.

b.Kugwiritsa ntchito mosalunjika kwa kusinthidwa kwa pulasitiki kumaphatikizapo kusinthidwa kuti apititse patsogolo kuthamanga kwa mapulasitiki popititsa patsogolo kumamatira, kusindikiza ndi kupukuta kwa mapulasitiki.Kutenga zokongoletsa electroplating pa pulasitiki monga chitsanzo, kokha ❖ kuyanika fastness wa ABS akhoza kukwaniritsa zofunika mapulasitiki popanda pamwamba mankhwala;Makamaka mapulasitiki a polyolefin, kuthamanga kwa zokutira ndikotsika kwambiri.Kusintha kwapamtunda kuyenera kuchitidwa kuti azitha kuphatikizira mwachangu ndi zokutira pamaso pa electroplating.

Zotsatirazi ndi zida zodzikongoletsera zasiliva zonyezimira bwino: khoma lawiri 30g 50gkirimu mtsuko, 30ml watsitsidwabotolo la dropperndi 50mlbotolo la lotion.
