Umurongo wo gukuramo imiyoboro ya OPVC

PVC {{} Imiyoboro ikorwa hifashishijwe ikoranabuhanga ryihariye ryo gutunganya icyerekezo, kandi imiyoboro ya PVC - U ikorwa nuburyo bwo gukuramo ibicuruzwa ikorerwa kurambura axial na radial, ku buryo molekile ya PVC ndende - mu miyoboro itunganijwe mu buryo busanzwe mu cyerekezo cya biaxial, bikavamo ubwoko bushya bwumuyoboro wa PVC ufite imbaraga nyinshi, ubukana bukabije, hamwe n’umuvuduko mwinshi.

Molekile nyinshi za polymer zirashobora gutondekwa muburyo busanzwe binyuze mugutunganya icyerekezo (bizwi kandi nkicyerekezo), bishobora kuzamura imitekerereze yabo. Mubyukuri, inyungu zo guhatanira ibicuruzwa byinshi bya pulasitike ku isoko zishingiye ku mikorere myiza yazanywe no gutunganya ibyerekezo, nka fibre, firime irambuye ya biaxial, kontineri, nibindi. Tekinoroji yo gutunganya icyerekezo irashobora kunoza imikorere yimiyoboro kuruhande rumwe, kandi igabanya imikoreshereze yibikoresho kurundi ruhande, aribwo buryo bwo guca - buhanga bujyanye nicyerekezo cyiterambere rirambye. Imiyoboro ya polyvinyl ya chloride (PVC - O) ikorwa hifashishijwe ikoranabuhanga ryihariye ryo gutunganya icyerekezo. Ubu buryo bwo gutunganya bukubiyemo kurambura imiyoboro ya PVC - U ikorwa no gusohora, ku buryo molekile ndende ya PVC mu miyoboro itunganijwe mu buryo busanzwe mu cyerekezo cya biaxial, bikavamo ubwoko bushya bwumuyoboro wa PVC ufite imbaraga nyinshi, ubukana bwinshi, kurwanya ingaruka nyinshi, no kurwanya umunaniro. Imikorere yayo irarenze kure imiyoboro isanzwe ya PVC - U. Ubushakashatsi niterambere rya PVC - O imiyoboro irashobora kuzigama cyane umutungo wibanze, kugabanya ibiciro, kunoza imikorere yibicuruzwa, kandi bifite inyungu zikomeye mubukungu n'imibereho myiza.

Mu minsi ya mbere, tekinoroji yo gutunganya "kumurongo" (uburyo bubiri - uburyo bwo gutunganya intambwe) yakoreshejwe kugirango yerekane ibice bya PVC - U byashyizwemo kandi bikonje (byambaye ubusa) ukoresheje ubushyuhe nogukwirakwiza umuvuduko kugeza mubunini busabwa imbere mubibumbano. Ubushakashatsi bwakozwe nubushakashatsi bufatika bwerekanye ko PVC - O ifite imikorere idasanzwe, ariko tekinoroji yo gutunganya "kumurongo" ifite umuvuduko muke wumusaruro, ishoramari ryibikoresho byinshi, kandi biragoye kuyiteza imbere. Nyuma, yatunganijwe yerekeza PVC - O muburyo bwa "kumurongo" mugihe cyo gutunganya ibicuruzwa, bituma habaho umusaruro wa PVC - O. Uburyo bwo kubyaza umusaruro ni bumwe - uburyo bwo gutunganya intambwe, burimo gukuramo imiyoboro ya PVC - U (imyenda yuzuye) kumurongo wo gukuramo imiyoboro kugirango ugere ku cyerekezo cya biaxial binyuze mu kwaguka kwa radiyo no kurambura axial, hanyuma gukonjesha no kubihindura mu miyoboro ya PVC - O. "Kumurongo" biaxial yerekanwe mubikorwa byongera umusaruro cyane, bigabanya ibiciro byinganda, kandi bizamura ubushobozi bwa PVC - O nindi miyoboro.

Bitewe nuko imiyoboro ya PVC - O O ikorerwa imiyoboro ya axial na radial irambuye ya PVC - U yashizweho mbere, uburebure bwurukuta rwimiyoboro ni nto. Ugereranije na PVC - U, PVC - O imiyoboro itanga amazi irashobora kugabanya uburebure bwurukuta kuri 35% -40%, bikabika cyane ibikoresho kandi bikagabanya ibiciro.

Nyuma yo kurambura biaxial, imbaraga zingaruka za PVC - U imiyoboro itanga amazi yiyongereyeho inshuro zirenga 10. Iyindi nyungu ya PVC - O imiyoboro ni uko kubera guhangayikishwa cyane nigishushanyo mbonera, byongera ubushobozi bwamazi, bigatuma byoroha kubyitwaramo no kuryama.

Impinduka niterambere mubihe mpuzamahanga byatanze amahirwe atigeze abaho mumateka yo guteza imbere imiyoboro ya PVC y'Ubushinwa. Kuzamuka gukabije kw'ibiciro bya peteroli byagize ingaruka zikomeye kuri sisitemu y'imiyoboro ya polyolefin ihanganye na sisitemu y'imiyoboro ya PVC mu bice byinshi bikoreshwa, mu gihe PVC ishingiye ku makara yazamuye ubushobozi bwayo mu gukomeza ibiciro biri hasi. Sisitemu ya PVC ifite amateka yiterambere mumyaka hafi 70. Bitewe ninyungu zayo nka modulus yo hejuru, imbaraga nyinshi, nigiciro gito, yamye ari uburyo bwo gukoresha imiyoboro ya pulasitike ikoreshwa cyane kwisi kandi yakoreshejwe henshi mubice byinshi bya societe igezweho. Inganda zikoresha imiyoboro ya pulasitike mu Bushinwa zateye imbere byihuse kandi zabaye kimwe mu bihugu bikomeye ku isi mu gukora no gukoresha imiyoboro ya pulasitike. Ubushobozi bwo gukora imiyoboro ya PVC mu Bushinwa burenga toni miliyoni 2 ku mwaka, bingana na 50% gusa by’umusaruro rusange wa pulasitiki. Mu bihugu byateye imbere, ikoreshwa ry'imiyoboro ya PVC muri rusange rifite 70% -80% by'isoko ry'imiyoboro ya plastiki. Mu kinyejana cya 21, imiyoboro ya PVC ihura nabanywanyi benshi, cyane cyane kubera iterambere ryinshi mumikorere ya resin nka HDPE (nko kuva PE63 kugeza PE80 na PE100). Imiyoboro ya PE ifite ubukana buhebuje no kurwanya ingaruka zinyundo. Byongeye kandi, kunenga chlorine n’imiryango ishinzwe kurengera ibidukikije mu bihugu bitandukanye yashyize imiyoboro ya PVC mu bihe bikomeye. Ariko, icyo abantu bagiye birengagiza kuva kera nuko imiyoboro ya PVC ikora neza mukurinda kwinjira mubintu bimwe na bimwe byangiza kandi byangiza ugereranije nu miyoboro ya PE. Mu gihe kizaza ku isoko ry'imiyoboro y'isi, imiyoboro ya PVC iracyiganje, kandi impamvu y'ibanze iri mu guhanga udushya no gutera imbere. Ikoreshwa rya tekinoroji igezweho mu miyoboro ya PVC no mu miyoboro ya PVC, cyane cyane guhanga udushya mu buhanga bwo gutunganya imiyoboro ya PVC, byateje imbere ubukungu bw’imiyoboro ya PVC kandi bifungura ahantu hashya hashyirwa ingufu. Birakenewe rero kubika ibikoresho mugihe tunoza imikorere yimiyoboro ya PVC kugirango bongere ubushobozi bwabo.

Umwanzuro:Bitewe nuburyo butandukanye budasanzwe, burambye budasanzwe, nubukungu, PVC izakomeza kuba ibikoresho byatoranijwe kumiyoboro iri imbere. Nubwoko bushya bwibikoresho, PVC - O ifite ibyiza byo gukora neza, igiciro gito, uburemere bworoshye, gukora byoroshye no gushira. Imikorere yayo ikomeye cyane iyemerera gukoreshwa kumuvuduko mwinshi hamwe nibidukikije bikaze.

PVC - O imashini ikuramo imiyoboro irashobora kubyara PVC - O ingano yubunini buri hagati ya Ø110 kugeza 3030mm kuri PN5 kugeza 25, hamwe nicyiciro cya 315 kugeza 500. PVC {{8} igiciro, imyanda mike. Imashini ikora imashini ya OPVC 1.Ibikoresho byo gusimbuza bishobora kubyara imiyoboro ifite diametero zitandukanye . 2. Hamwe nimikorere yabibumbano kugirango itange imiyoboro ibiri cyangwa ine icyarimwe. Kongera umusaruro ushimishije . 3. Igiciro kinini - umurongo utanga umusaruro . 4. Kuzigama cyane imikoreshereze yumwanya wuruganda . 5. Gukoresha ingufu nyinshi. Gusa urutonde rwamashanyarazi . 6. Irashobora kugabanya cyane umubare wabakoresha . 7. Igikorwa cyoroshye.
