Bag kugadzira muchina muchina wekugadzira marudzi ese emabhegi epurasitiki kana mamwe mabhegi. Kugadziriswa kwayo kwakasiyana marudzi ese epurasitiki kana mamwe mabhegi emidziyo ane hukuru hwakasiyana, ukobvu uye zvakatemwa. Kazhinji kutaura, mabhegi epurasitiki ndiwo zvigadzirwa zvikuru.
Plastic bag kugadzira muchina
1. Kuronga uye kushandiswa kwehombodo dzepurasitiki
1. Mhando dzehombodo dzepurasitiki
(1) High pressure polyethylene plastic bag
(2) Low pressure polyethylene plastic bag
(3) Polypropylene plastic bag
(4) PVC purasitiki bhegi
2. Kushandisa mabhegi epurasitiki
(1) Chinangwa cheyakanyanya kudzvanywa polyethylene bhegi repurasitiki:
A. Kurongedza chikafu: makeke, zvihwitsi, zvinhu zvakakangwa, mabhisikiti, hupfu hwemukaka, munyu, tii, nezvimwewo;
B. Fiber packaging: shati, zvipfeko, tsono zvigadzirwa zvekotoni, makemikari fiber zvigadzirwa;
C. Packaging yemishonga yemazuva ose.
(2) Chinangwa cheyakaderera kumanikidza polyethylene epurasitiki bhegi:
A. Tsvina bhegi uye strain bag;
B. bhegi rekurerutsa, bhegi rekutenga, handbag, vest bag;
C. Bag idzva rekuchengeta;
D. Yakarukwa bhegi remukati bhegi

(4) Kushandiswa kwePVC mabhegi epurasitiki: A. mabhegi ezvipo; B. Mabhegi emitoro, tsono donje zvigadzirwa packaging mabhegi, zvizorwa packaging mabhegi;
C. (zipper) gwaro bhegi uye data bag.
2.Kuumbwa kwepurasitiki
Plastiki yatinowanzo shandisa haisi chinhu chakachena. Yakagadzirwa nezvinhu zvakawanda. Pakati pavo, high molecular polymer (kana synthetic resin) ndiyo chikamu chikuru chepurasitiki. Mukuwedzera, kuti uvandudze kushanda kwemapurasitiki, zvakakosha kuwedzera zvinhu zvakasiyana-siyana zvekubatsira, zvakadai semafirita, mapurasitiki, mafuta, stabilizers uye mavara, kuitira kuti ave mapurasitiki ane basa rakanaka.
1. Synthetic resin
Synthetic resin ndicho chinhu chikuru chepurasitiki, uye zvirimo mumapurasitiki zvinowanzo 40% ~ 100%. Nekuda kwehuwandu hwayo hwepamusoro uye chimiro cheresin chinowanzo tarisa chimiro chepurasitiki, vanhu vanowanzo tora resin serinofanana nemapurasitiki. Semuenzaniso, PVC resin uye PVC plastiki, phenolic resin uye phenolic plastiki inovhiringidzika. Muchokwadi, resin nepurasitiki ipfungwa mbiri dzakasiyana. Resin ndeye isina kugadziridzwa yekutanga polymer. Haisi kungoshandiswa kugadzira mapurasitiki chete, asi zvakare inoshandiswa seyakasvibirira machira ekuputira, adhesives uye synthetic fibers. Pamusoro pechikamu chidiki chemapurasitiki ane 100% resin, mazhinji epurasitiki anoda kuwedzera zvimwe zvinhu mukuwedzera kune chikuru chikamu resin.
2. Filler
Mafirita, anozivikanwawo semafirita, anogona kuvandudza simba uye kupisa kupisa kwemapurasitiki uye kuderedza mutengo. Semuenzaniso, kuwedzerwa kwehuni hupfu kune phenolic resin kunogona kuderedza zvakanyanya mutengo, kuita phenolic plastiki imwe yemapurasitiki akachipa, uye zvakanyanya kunatsiridza simba remuchina. Mafirita anogona kupatsanurwa kuita organic mafirita uye inorganic mafirita, ekutanga senge huni hupfu, mamvemve, pepa uye akasiyana machira machira, uye ekupedzisira senge girazi fiber, diatomite, asbestos, kabhoni nhema, nezvimwe.
3. Plasticizer
Plasticizers anogona kuwedzera mapurasitiki uye kupfava kwepurasitiki, kuderedza brittleness uye kuita kuti mapurasitiki ave nyore kugadzira uye kuumbwa. Plasticizers anowanzo kubikira organic komisheni iyo inosanganiswa neresin, isiri-chepfu, isinganhuhwi uye yakagadzikana kuchiedza nekupisa. Phthalates ndiyo inonyanya kushandiswa. Semuenzaniso, mukugadzirwa kwePVC plastiki, kana mamwe mapurasitiki akawedzerwa, mapurasitiki akapfava ePVC anogona kuwanikwa. Kana pasina kana mapurasitiki mashoma akawedzerwa (dosage <10%), yakaoma PVC mapurasitiki anogona kuwanikwa.
4. Stabilizer
Kuti udzivise resin yakagadzirwa kubva pakuora uye kukuvadzwa nechiedza uye kupisa mukugadzirisa uye kushandiswa, uye kuwedzera hupenyu hwebasa, stabilizer inofanira kuwedzerwa kupurasitiki. Inonyanya kushandiswa ndeye stearate, epoxy resin, nezvimwe.
5. Colorant
Mavara anogona kugadzira mapurasitiki ave neakasiyana akajeka uye akanaka mavara. Organic dhayi uye inorganic pigments inowanzoshandiswa semavara.
6. Lubricant
Basa remafuta nderokudzivirira purasitiki kuti isanamatira kune simbi mold panguva yekuumbwa, uye kuita kuti nzvimbo yepurasitiki iite zvakanaka uye yakanaka. Mafuta akajairika anosanganisira stearic acid uye ayo calcium magnesium munyu.
Pamusoro pezvinowedzera zviri pamusoro, zvinodzosa moto, zvinopupa furo uye antistatic agents zvinogonawo kuwedzerwa kumapurasitiki kuti asangane nezvinodiwa zvakasiyana zvekushandisa.
Muchina wekugadzira bhegi
Nguo yebhegi inoreva bhegi rakagadzirwa neOPP firimu kana PE, PP uye CPP firimu, isina inonamira firimu painopinza uye yakavharwa mativi ese.
Chinangwa:
Isu tinowanzoshandiswa kurongedza mbatya dzezhizha, sehembe, masiketi, matirauzi, mabhanzi, matauro, chingwa nemabhegi ezvishongo. Kazhinji, rudzi urwu rwebhegi rine self-adhesive pairi, iyo inogona kuiswa chisimbiso zvakananga mushure mekuiswa muchigadzirwa. Mumusika wepamba, rudzi urwu rwebhegi rinofarirwa zvakanyanya uye rinoshandiswa zvakanyanya. Nekuda kwekujeka kwayo kwakanaka, zvakare isarudzo yakanaka yekurongedza zvipo.
