Imodeli eluncedo ibhekiselele kwingxowa yesamente ehlanganisiweyo eyenziwe ngomnatha elukiweyo eyenziwe ngeplastiki, apho umaleko osembindini wayo uyisilika enithiweyo eyenziwe ngeeplastiki ezinepolypropylene. Phakathi kwezi, i-polypropylene ithathwa njengeyona nxalenye ibalulekileyo yenkqubo yokwenziwa kweengxowa zeplastiki zesamente kwaye ichaphazela umgangatho wokupakishwa. Masifumanise imathiriyeli yeengxowa zokupakisha zesamente kunye nenkqubo yokwenziwa kweengxowa zeplastiki zesamente.

Umsonto wePP –> Ishiti elilukiweyo lelaphu lePP –> ifilimu elaphu eligqunyiweyo lePP –> Iprintwa kwiingxowa zePP –> Iimveliso ezigqityiweyo (ukuwelda emoyeni oshushu).
Umgca wokuvelisa ingxowa yesamente uveliswa phantsi kwenkqubo enzima kakhulu.

1.Yenza umsonto wePP

Iigranule zeplastiki zePP zilayishwa kwi-hopper yesixhobo sokwenza umsonto, ngomatshini wokufunxa ofakwe kwi-extruder, kwaye ushushu ukuze unyibilike. Isikrufu sikhupha iplastiki engamanzi kumlomo wokungunda ngobude obuhlengahlengiswayo kunye nobukhulu njengoko kufuneka, kwaye ifilimu yeplastiki yenziwa ngokubumba ibhafu yamanzi okupholisa. Emva koko ifilimu ingena kwi-cutter shaft ukuze inqunyulwe kububanzi obufunekayo (2-3 mm), umsonto uhamba nge-heater ukuze uzinziswe kwaye ubekwe kumatshini ojikelezayo.

Kwinkqubo yokudala intambo, inkunkuma yefiber kunye ne-bavia yefilimu yeplastiki ifunyanwa ngokufunxa, inqunyulwe ibe ngamaqhekeza amancinci, kwaye ibuyiselwe kwi-extruder.

2.Ilaphu elilukiweyo lePP

Imiqulu yePP ifakwa kwi-shuttle ye-shuttle loom esetyhula ukuze ilukwe kwiityhubhu zelaphu zePP, ngendlela yokujija ilaphu lePP.

3.Ifilimu yelaphu yePP egqunywe

I-PP yelaphu roll ifakwe yiloli ye-forklift kumatshini wokugquma ifilimu, i- sheet sheet ye-PP ifakwe ngobunzima be-30 ye-plastiki ye-PP ukunyusa ibhondi yelaphu elinobumanzi. Umqulu welaphu lePP eligqunywe kwaye liqengqeleke.

4.Ukushicilelwa kwiingxowa zePP

Ifilimu ye-OPP yokunyibilika yeyona bhegi intle kwaye intle, itekhnoloji yoshicilelo lwegravure kwifilimu ye-OPP, emva koko ihlomele le filimu kumqulu welaphu elilukiweyo lePP.

5.Ukusika imveliso egqityiweyo kunye nokupakisha

Iingxowa ezingaprintwayo okanye ze-Flexo eziprintiweyo zePP ezilukiweyo: Imiqulu yePP elukiweyo idluliswa kwinkqubo yokugoqa i-hip (ukuba ikhona), kwaye imveliso egqityiweyo iyasikwa. Thunga kuqala, uprinte kamva, okanye uthunge kamva, printa kuqala. Iimveliso ezigqityiweyo zihamba ngokubala okuzenzekelayo kunye nokupakishwa kweebhali.

Iingxowa ezilukiweyo zePP ezinefilimu yoshicilelo yegravure kwimiqulu zigqithiswa kwinkqubo ezenzekelayo yokusonga icala, ukucinezela komphetho, ukusika, ukuthunga okusezantsi, kunye nokupakisha.

Ngamafutshane, i-polypropylene polymer yinto ekhethiweyo ngexesha lokwenziwa kweengxowa zeplastiki zesamente xa kuziwa kwimveliso yokupakisha iingxowa zesamente. Ukugcinwa, ukuthuthwa, kunye nokuphathwa kwesamente yiyo yonke imisebenzi exhamlayo kwizinto eziphathekayo, iikhemikhali, kunye neepropati ze-polypropylene.

Iinkcukacha zeengxowa zesamente:

Iingxowa ezilukiweyo zithetha kakhulu: iingxowa ezilukiweyo zeplastiki zenziwe ngepolypropylene (PP ngesiNgesi) njengeyona nto iphambili ekrwada, ethi ikhutshelwe kwaye yolulwe ibe ngumsonto osicaba, emva koko ilukwe, ilukwe, kwaye yenziwe ibhegi.
