Iyini i-PP Material ?
I-Polypropylene (PP), eyaziwa nangokuthi i-polypropene, iyi-polymer ye-thermoplastic esetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza ezihlanganisa ukupakisha nokulebula, izindwangu (isb., izintambo, izingubo zangaphansi ezishisayo kanye nokhaphethi)
Iyavumelana nezimo futhi iqinile, ikakhulukazi uma ihlanganiswe ne-ethylene.
Lokhu kuhlanganiswa kwe-copolymerization kuvumela le pulasitiki ukuthi isetshenziswe njengepulasitiki yobunjiniyela esemikhiqizo eminingi nokusetshenziswa okuhlukahlukene. Izinga lokugeleza liyisilinganiso sesisindo samangqamuzana futhi lokhu kunquma ukuthi lizogeleza kalula kangakanani phakathi nokucubungula. Ezinye zezinto ezibaluleke kakhulu ze-polypropylene yilezi: Ukumelana Namakhemikhali: Izisekelo ezixutshiwe nama-asidi akusabeli kalula nge-polypropylene, okwenza kube ukukhetha okuhle kweziqukathi zoketshezi olunjalo, njengama-ejenti okuhlanza, imikhiqizo yosizo lokuqala, nokunye.
Imele ini i-GSM?
Imele ukushuba kwesikhwama. Ngokuvamile kunzima ngathi ukusebenzisa amasentimitha achaza ukushuba kwesikhwama, kodwa kulula kakhulu ngathi ukukuqonda ngesisindo sesikhwama. Futhi i-GSM okusho ukuthi igramu yesikhwama ngemitha yesikwele yaziwa yithi. I-GSM evamile esiyisebenzisela isikhwama esilukiwe se-pp isuka ku-42 gsm iye ku-120 gsm. Idijithali inkulu, ukujiya kukhudlwana. Ungase ukhethe ukujiya ngokusekelwe imfuneko yakho. Isibonelo, umthamo wezinto mkhulu futhi isisindo asisindi, ungakhetha i-GSM engenkulu kangako futhi intengo ishibhile. Kodwa uma ukhetha ukulayisha izinto ngevolumu encane kodwa isisindo esinzima, i-GSM enkulu iyadingeka.
Kungani amasaka we-Pp Woven enokuqina namandla okuhlukile?
Ukuqina namandla konke kusekelwe ekuqineni kwesikhwama esilukiwe se-pp. I-tension ungachazwa ngokuthi uyidonsa ngamandla uma uyinweba uye phezulu. Iyunithi ye-tension "N" , enkulu ye-N, inamandla esikhwama. Ngakho-ke uma uthemba i-N yesikhwama, futhi singakubonisa umphumela wokuhlola.
Kuyini ukuphrinta kwe-offset nokuphrinta umbala?
Ukuphrinta kwe-offset kuyindlela elula yokuphrinta ilogo yakho, ngaphambi kokuthi senze i-offset, sizokwenza isikhunta selogo yakho bese sinamathisela isikhunta ebhakedeni eligoqayo lombala. Izinzuzo zokuphrinta kwe-offset ukuthi, kulula ukusebenza, kushibhile ukwenza amasampula, ukungalungi: imibala ayikwazanga ukuba ngaphezu kuka-4 futhi umbala awukhanyi njengokuphrinta kombala. Kodwa ukuphrinta kombala kungaba okuningi ngendlela ofisa ngayo. Isebenzisa i-opp laminated ukumboza ubuso besikhwama esilukiwe se-pp, ukuze imibala iguquke kakhulu, umphumela wombala muhle kakhulu. Kunzima ukwenza isampula yokuphrinta, futhi imali yokubumba iyabiza kunokuphrinta kwe-offset.
Kungani isikhwama se-laminated pp singenamanzi?
Uma isikhwama sokwelukwa se-pp sine-laminated, okusho ukuthi ingaphezulu lesikhwama se-pp linepulasitiki elincanyana kakhulu le-op. I-opp ayinamanzi. Vele, singafaka isikhwama se-Pe liner ezikhwameni ze-pp, futhi singangenwa amanzi.
