Kongera gukoresha chloride ya polyvinyl

Polyvinyl chloride nimwe mubintu bitanu byingenzi bigamije rusange kwisi.Bitewe nigiciro gito cyumusaruro ugereranije na polyethylene hamwe nibyuma bimwe na bimwe, hamwe nuburyo bwiza bwo gutunganya nibikorwa byumubiri nubumara byibicuruzwa, birashobora guhaza ibikenewe byo gutegura bigoye byoroshye, byoroshye, byoroshye, fibre, coating nibindi bintu, kandi bikoreshwa cyane mubice bitandukanye nkinganda, ubuhinzi, nubwubatsi.Uburyo bwo gutunganya no gukoresha imyanda polyvinyl chloride ni ngombwa cyane.
1.Ubuvuka bushya
Ubwa mbere, kuvuka bundi bushya birashobora gukorwa.Kuvugurura mu buryo butaziguye imyanda ya plastike bivuga gutunganya no kubumba mu buryo butaziguye imyanda ya plastiki binyuze mu gusukura, kumenagura, no kuyitunganya bidakenewe ko hahindurwa ibintu bitandukanye, cyangwa gutunganya no kubumba ibicuruzwa binyuze muri granulation.Mubyongeyeho, irashobora kandi guhindurwa no kuvugururwa.Guhindura no kuvugurura plastiki ishaje bivuga guhindura umubiri na chimique bya plastiki ikoreshwa mbere yo kuyitunganya no kuyikora.Guhindura birashobora kugabanywa muburyo bwo guhindura umubiri no guhindura imiti.Kuzuza, fibre ikomatanya, hamwe no kuvanga gukomera nuburyo nyamukuru bwo guhindura umubiri wa PVC.Kuzuza impinduka bivuga uburyo bwo guhindura uburyo bwo kuvanga ibice bimwe byuzuza impinduka hamwe na modulus yo hejuru cyane muri polymers.Guhindura fibre yibikoresho byerekana uburyo bwo guhindura uburyo bwo kongeramo modulus nyinshi nimbaraga nyinshi za fibre naturel cyangwa artificiel muri polymer, bityo bikazamura cyane imiterere yibicuruzwa.Guhindura imiti ya PVC bigerwaho muguhindura imiterere ya PVC binyuze mumiti imwe n'imwe.
2.Gukuraho no gukoresha hydrogen chloride
PVC irimo chlorine igera kuri 59%.Bitandukanye nandi mashanyarazi ya karubone, urunigi rwishami rwa PVC ruvunika mbere yuruhererekane runini mugihe cyo guturika, rukabyara gaze ya hydrogène chloride nyinshi, izangiza ibikoresho, ikangiza uburozi bwa Catalyst, kandi ikagira ingaruka kumiterere yibicuruzwa byacitse.Kubwibyo, hydrogen chloride yo kuvanaho igomba gukorwa mugihe cya PVC.
3. Gutwika PVC kugirango ukoreshe ubushyuhe na gaze ya chlorine
Kuri plastiki yimyanda irimo PVC, ibiranga kubyara ubushyuhe bwinshi bikoreshwa muburyo bwo kubivanga n imyanda itandukanye yaka kandi bigatanga ibicanwa bikomeye bifite ubunini buke.Ibi ntabwo byorohereza kubika no gutwara gusa, ahubwo binasimbuza lisansi ikoreshwa mu gutwika amakara no mu ziko ry’inganda, ikanagabanya chlorine kugirango iteze imbere ubushyuhe.
