Polypropilene (PP) ni thermoplastique "yongeyeho polymer" ikozwe mu guhuza monomeri ya propylene. Ikoreshwa mubikorwa bitandukanye kugirango ushiremo gupakira ibicuruzwa byabaguzi, ibice bya pulasitike mu nganda zitandukanye zirimo inganda z’imodoka, ibikoresho bidasanzwe nka hinges nzima, hamwe n’imyenda.
1. Kuvura plastiki.
PP yera ni amahembe yinzovu yera kandi irashobora gusiga amabara atandukanye. Kurangi PP, gusa ibara ryibara rishobora gukoreshwa muri rusangegushushanya inshingeimashini. Ibicuruzwa bikoreshwa hanze muri rusange byuzuyemo UV stabilisateur na karubone yumukara. Ikigereranyo cyo gukoresha ibikoresho bitunganijwe ntigishobora kurenga 15%, bitabaye ibyo bizatera imbaraga kugabanuka no kubora no guhinduka amabara.
2. Guhitamo imashini ibumba inshinge
Kuberako PP ifite kristu yo hejuru. Imashini itera imashini ya mudasobwa ifite umuvuduko mwinshi wo gutera no kugenzura ibyiciro byinshi. Imbaraga zo gufatira muri rusange zagenwe kuri 3800t / m2, naho inshinge ni 20% -85%.
3. Igishushanyo mbonera n'irembo
Ubushyuhe bwububiko ni 50-90 ℃, nubushyuhe bwo hejuru bukoreshwa mubisabwa hejuru. Ubushyuhe bwibanze burenze 5 ℃ munsi yubushyuhe bwa cavity, diameter yiruka ni 4-7mm, uburebure bw irembo ryurushinge ni 1-1.5mm, kandi diameter irashobora kuba nto nka 0.7mm. Uburebure bw irembo ryuruhande ni bugufi bushoboka, hafi 0.7mm, ubujyakuzimu ni kimwe cya kabiri cyubugari bwurukuta, naho ubugari bwikubye kabiri uburebure bwurukuta, kandi bizagenda byiyongera buhoro buhoro hamwe nuburebure bwamazi ashonga mu cyuho. Ifumbire igomba kugira umuyaga mwiza. Umwobo wa vent ni 0.025mm-0.038mm z'uburebure na 1.5mm z'ubugari. Kugira ngo wirinde kugabanuka, koresha uruziga runini kandi ruzengurutse uruziga ruzenguruka, kandi ubunini bwimbavu bugomba kuba buto. Ubunini bwibicuruzwa bikozwe muri homopolymer PP ntibishobora kurenga 3mm, bitabaye ibyo hazabaho ibibyimba.
4. Gushonga ubushyuhe
Ahantu ho gushonga kwa PP ni 160-175 ° C, naho ubushyuhe bwangirika ni 350 ° C, ariko ubushyuhe ntibushobora kurenga 275 ° C mugihe cyo gutunganya inshinge. Ubushyuhe bwakarere gashonga nibyiza 240 ° C.
5. Umuvuduko wo gutera inshinge
Kugirango ugabanye imihangayiko yimbere no guhindura ibintu, hagomba gutorwa inshinge yihuta, ariko amanota amwe ya PP nububiko ntibikwiye. Niba ubuso bugaragara bugaragara hamwe numurongo wijimye kandi wijimye ukwirakwizwa n irembo, inshinge nkeya hamwe nubushyuhe bwo hejuru bugomba gukoreshwa.
6. Shonga umuvuduko winyuma
5bar gushonga ibyuma byinyuma birashobora gukoreshwa, kandi umuvuduko winyuma wibikoresho bya toner urashobora guhinduka muburyo bukwiye.
7. Gutera inshinge no gukomeza igitutu
Koresha umuvuduko mwinshi (1500-1800bar) kandi ufate igitutu (hafi 80% yumuvuduko watewe). Hindura gufata igitutu hafi 95% ya stroke yuzuye, hanyuma ukoreshe umwanya muremure.
8. Nyuma yo gutunganya ibicuruzwa
Kugirango wirinde kugabanuka no guhindura ibintu biterwa na nyuma ya kristu, ibicuruzwa muri rusange bigomba gushiramod mumazi ashyushye.
