PVC pipe, ibikoresho bya plastiki bikoreshwa cyane mu kubaka igezweho no mu nyego z'ubuhanga, harimo amahitamo y'amazi no kuvoma kw'amashanyarazi, no kuhira amashanyarazi, tubikesha imikorere myiza. Nyuma yimyaka myinshi indorerezi nubushakashatsi bwa tekiniki, umwanditsi yavuganye muri make uburambe bwinshi bwo gutoranya PVC, kwishyiriraho, no kubungabunga, bisobanuwe neza hepfo.
I. Ibiranga Ibikoresho no Guhitamo ingingo zingenzi
PVC Pipe, ngufi kuri polyviny ya chlolodide, irashobora kugabanywa muri PVC ya Rigid (UPVC) na PVC ihindagurika ishingiye kuri plastisar. UPVC ikoreshwa cyane cyane mumyitozo yubuhanga kubera ibiranga imbaraga za kanseri yimbaraga zidasanzwe zirenze cyangwa zingana na 45 m.-} Mugihe cyo gutoranya, kwibanda kubice bikurikira: Kwihanganira umuyoboro uhanganira GB / T 10002.1, hamwe nubwinshi bwurukuta rwigandukira imbere ± 10%. Ku miyoboro y'ingutu, igipimo gikomeye cya Hoop kigomba kugenzurwa (SN4 / SN8 / SN16 gihuye nibisabwa bitandukanye byimbitse). Imiyoboro y'isuku igomba gutanga uruhushya rwisuku, kandi ibirimo byo kuyobora ntibigomba kurenga 0.001 mg / l.
Birakwiye ko tumenya ko guhuza guhuza PVC imiyoboro ya PVC yakozwe nabakora ibintu bitandukanye biratandukanye. Mu mushinga umwe wa komini, kuvanga ikiranga hamwe na socket ya Brand B yavuyemo 23% bihuriweho. Ibi byakemuwe no gukoresha ikoreshwa ryibikoresho bihuye bivuye ku kirango kimwe. Birasabwa ko abatanga isoko ryuzuye batanga ibyangombwa byuzuye kandi bakora igenzura mugihe bagura igice kinini.
II. Tekinike y'ingenzi no kwishyiriraho
Imiyoboro igomba kugabanywa ukoresheje PVC yeguriwe cyangwa inguni. Gukata bigomba kuba byoroshye kandi birr - kubuntu. Inguni yangiza impamyabumenyi 2 irashobora gutera imihangayiko ihindagurika. Ishyushye - Gusoza inzira ihuza ubushyuhe bukabije (200 -} 220. Ubushyuhe bukabije bushobora gutera kubora ibikoresho no kubyara gaze ya hydrogen. Kuri sock-na spigot ihuza, kwinjiza ikibanza cyimbitse bigomba guhinduka hamwe na sock imbonankubone. Mubyukuri, hagereranywa 15% byibyabaye biterwa no kwinjiza bidahagije.
Kubishirizwa ku nkubera, amabwiriza asaba ko ingano ya seckfill idashobora kurenga 1/3 cyumuyoboro wa dipera, kandi ko 150mm umubyimba wijimye utagomba kubamo ibintu bikomeye nkibigata byacitse. Mu mushinga w'imvura yo guturamo umuyoboro wubucuruzi, guhuza bidahagije byavuyemo igipimo cyo gutura kitari hafi 3%. Nyuma, Pierste bengeweho yo gushimangira. Kubwumuyoboro washyizwe ahagaragara, ubwitonzi bugomba kuba munsi cyangwa ingana na 1.2m itambitse kandi iri munsi cyangwa ingana na 1.5m ihagaritse kuri dn25. Ingingo yinyongera ya Ankeri igomba gutangwa.
III. Gusuzuma Ikibazo Rusange no Kubungabunga
Impunzi zisanzwe za PVC zirimo umurongo uhuriweho, urukuta rwa pie, urusaku rw'amazi. Kumeneka mu ngingo birashobora gufungwa by'agateganyo hamwe na PVC kumeneka, ariko gusana burundu biracyasaba kubona no guhura. Umuyoboro uhinduka akenshi bibaho mubushyuhe bukonje. Iyo ubushyuhe bwibidukikije bugwa munsi yimpamyabumenyi 5, hagomba gushyirwa mubikorwa cyangwa ubukonje -} umuyoboro wa pvc (ubushyuhe bwuzuye (ubushyuhe buke) bigomba gukoreshwa. Urusaku rw'amazi rushobora gukemurwa no kongeramo ibikoresho byangiza (nka gasket ya rubber) cyangwa guhindura igipimo cyuruzi (birasabwa kubungabunga 0.8-1.5 m / s).
Ubugenzuzi buri gihe bwo kubungabunga bugomba kubamo: Kugenzura bigaragara hejuru yumuyoboro kubice no kubyutsa; Gukoresha ubwumvikane kugirango umenye kumeneka; no kugerageza ubusugire bwa anti - rirsioni igikona kuri page yashyinguwe buri myaka itatu. Inyigisho y'urubanza muri parike y'inganda yerekanaga ko gushyira mu bikorwa uburyo bwo gucunga imiyoboro ya digitale bwagabanije igihe cyo gusubiza kunanirwa na 60% no kugabanya amafaranga yo gusana na 42%.
IV. Inzira yiterambere hamwe nibisabwa bishya
Imiyoboro mishya yahinduwe ya PVC ikomeza kwagura imipaka yabo: PVC {{0- imiyoboro yagira ingaruka ku masomo yabo yiyongereyeho 300%; Pvc -} o}} oupe ikoresha inzira ya biaxial inzira yabonye imbaraga zabo ziyongereye inshuro zirenga eshanu; Kandi intangiriro ya NanoCOMesites yashoboje imiyoboro ya antibacterial PVC kugirango igere ku kigero cya AntibaCorial 99%. Mu bwumvikane bwumujyi, uburyo bwubwenge bwa PVC bufite imiyoboro ihuriweho nigitutu byageze kuringaniza ikibanza cyuzuyemo hamwe nikosa rya metero 0,5.
Duhereye kubuhanga bwubukungu, mugihe ishoramari ryambere muri PVC rigera kuri 35% munsi yumuyoboro wicyuma, 50 {{{{{{}}} umwaka wose igiciro cyose nicyo giciro cyinshi. Nkuko igihugu cyanjye gisimbuye ibyuma "gikomeje gutera imbere, gahunda yikoranabuhanga ya PVC isanzwe izaba inkunga nyamukuru ishinzwe iterambere ryimiterere yibikorwa remezo.
