Chinhu chipi nechipi chinogona kuvandudza zvinhu zvepakutanga zve resin kuburikidza nemuviri, mechanical uye makemikari mhedzisiro inogona kunzikuchinjwa kwepurasitiki.Chirevo chekugadzirisa kwepurasitiki chakakura kwazvo.Munguva yekuchinja maitiro, zvese zvemuviri uye zvemakemikari shanduko zvinogona kuzviita.

Iyo inowanzoshandiswa nzira dzekugadzirisa mapurasitiki ndeaya anotevera:

1. Wedzera zvinhu zvakagadziridzwa

a.Wedzera diki-morekuru inorganic kana organic matter

Inorganic additives senge mafirita, anosimbisa maajenti, zvinodzosa moto, colorants uye nucleating agents, nezvimwe.

Organic additives zvinosanganisira plasticizers, organotin stabilizers, antioxidants uye organic flame retardants, Degradation additives, etc. Semuyenzaniso, Topfeel anowedzera zvinokonzeresa zvinokonzeresa kune mamwe mabhodhoro ePET kuti akurumidze kuderera uye kuparara kwemapurasitiki.

b.Kuwedzera polymer zvinhu

2. Kugadziriswa kwechimiro uye chimiro

Iyi nzira inonyanya kuitirwa kugadzirisa iyo resin fomu uye chimiro chepurasitiki pachayo.Iyo yakajairika nzira ndeyekuchinja kristaro mamiriro epurasitiki, crosslinking, copolymerization, grafting uye zvichingodaro.Semuenzaniso, styrene-butadiene graft copolymer inovandudza kukanganisa kwePS zvinhu.Iyo PS inowanzo shandiswa mudzimba dzeTV, midziyo yemagetsi, zvinyoreso zvebhora, marambi uye mafiriji, nezvimwe.

3. Compound modification

The composite modified of plastics inzira iyo maviri kana anopfuura akaturikidzana emafirimu, mashizha uye zvimwe zvinhu zvinosanganiswa pamwe chete nenzira yekunamatira kana inopisa kunyunguduka kuti iite yakawanda-layer firimu, sheet uye zvimwe zvinhu. epurasitiki cosmetic chubhu uyealuminium-plastic composite tubesdzinoshandiswa munyaya iyi.

4. Kugadziriswa kwepamusoro

Chinangwa chekugadziriswa kwepasi pepurasitiki chinogona kukamurwa kuita zvikamu zviviri: imwe inoshandisirwa zvakananga kushandurwa, imwe yacho isina kunanga inoshandiswa shanduko.

a.Yakanyatso shandiswa epurasitiki kugadziridzwa kwepasi kunosanganisira kupenya kwepamusoro, kuomarara kwepasi, kusagadzika kwepamusoro uye kukweshana, anti-kuchembera pamusoro, kupisa kwemoto retardant, conductivity yepasi uye chipingamupinyi chepasi, nezvimwe.

b.Iko kushandiswa kusina kunanga kwepurasitiki pamusoro pekugadzirisa kunosanganisira kugadziridzwa kwekuvandudza kusimba kwepamusoro kwepurasitiki nekuvandudza kunamatira, kudhindwa uye kunyunguduka kwepurasitiki.Kutora electroplating kushongedzwa papurasitiki semuenzaniso, iyo chete yekubatisa kukurumidza kweABS inogona kusangana nezvinodiwa zvepurasitiki pasina kurapwa kwepamusoro;Kunyanya kune polyolefin mapurasitiki, iyo coating fastness yakaderera zvakanyanya.Kugadziriswa kwepamusoro kunofanirwa kuitwa kuti uvandudze kukurumidza kusanganiswa nejasi pamberi pe electroplating.

Izvi zvinotevera seti yesirivha inopenya yakazara electroplated cosmetic containers: Double wall 30g 50gcream jar, 30ml yakadzvinyirirwadropper bhodhorouye 50mllotion bhodhoro.
