PVC - yintoni na? PVC ubugcisa bemveliso kunye nezicelo

Ukuba ukhetha ukusebenzisa ekwakhiweni okanye nokulungiswa PVC, kubalulekile ukwazi phambi kokusebenzisa imveliso. Le ebonakalayo ukuguda zokwenziwa thermoplastic.

iimpawu PVC

Xa kwimeko yase fektri yavelisa iintlobo ezimbini PVC, owokuqala apho plasticized, ngoxa yesibini - unplasticized. Kwimeko yokugqibela, kusetyenziswa plasticizer. Ngaphandle, PVC na uhlobo ngumgubo emhlophe leyo esha. It has a iipropati ezisemgangathweni kunye namandla eliphezulu dielectricity. Ukuba ugqiba ukuba uthenge PVC, oko kuyimfuneko ukufunda na. Kuyinto ayinyangeki alkalis,-oyile izimbiwa, ii-asidi, ezingenakunyibilika emanzini. Ukukhuthaza, ekumisweni kunye ketones ngokuzigwagwisa, esters, kunye hydrocarbon ibhedolaki ikhlorini. Izinto lunyamezela igcwala kwaye phantse lingatshi liphele. Polyvinyl chloride uye iimpawu enganyangekiyo ngakuba nomtsalane kakhulu ubushushu xa baboniswa lobushushu ka 100 degrees iqala ukubola. Ukuze kufikelelwe ukumelana nobushushu nokuphucula umgangatho ukunyibilika PVC boniswa chlorination.

Ububanzi bokusebenzisa

Namhlanje, kakhulu wafumana PVC ngokubanzi. Yintoni na wonke umntu kufuneka azi olungisa izinto kunye oyingcali kwicandelo lokwakha. Le nto isetyenziswa amayeza, ngokubuyisela zeglasi kunye zerabha. Ngenxa yoko, siye sakwazi ukufumana izinto ngexesha elinye. Ngenxa uyazinza imichiza kunye inertia, PVC iye yaphinda yathandwa phezulu kule ndawo. Products kuyo eyahlukeneyo ngokulula iveliswayo, kwaye sitshiphu ngaphezu izinto ezisetyenzisiweyo ngaphambili.

PVC isetyenziswa kwishishini zokuhamba. Oku kusetyenziswa ekuvelisweni panels ucango, iingalo, kwakunye nokudalwa cable usambathisa. Kanye ngenxa yale ngemoto ilifa ixesha elide lobomi, nto leyo yaligqiba kuthelekiswa namanani zangaphambili iminyaka emithandathu. Le ndlela iza kwandisa ukhuseleko zothutho, njengokuba PVC ezinokuvula airbag iipanele zokhuseleko, ezinako ukukulumkisela ukukhusela abakhweli ukulimala xa iingozi.

Ukulungiswa kunye nokwakhiwa

Ukuqwalasela lo chloride Polyvinyl ukuba unako ukufunda eli nqaku. Le nto lisetyenziswa namhlanje imboniselo kuyilo. ubonakele ngenxa yokuba ubugcisa bale mihla ikuvumela ukuba ukudala imveliso PVC nayiphi na imilo onjalo ithuba. Ngaloo ndlela, kuyenzeka ukuba wenze izinto zangaphakathi. Amaninzi, oku Polymer inokufumaneka sakhiwo. Ikhupha ukunxiba-resistant, iimveliso engqongqo, ayisindi ukuba ngokugqibeleleyo ukumelana ngokudleka kunye neziphumo imichiza. Loo ukuthandwa eliphezulu kwishishini lokwakha kwakhona ngenxa yomlilo ukhuseleko, izinto kunzima phemba zokumisa avuthayo, lungaqhubeka ngelixa ukuphelisa lobushushu umthombo. Kungenxa yoko le mveliso zingasetyenziswa kwi izinto, ezo iimfuno zokongezwa ukhuseleko emlilweni. PVC izinto luphawulwa uqinile, kwama-75 ekhulwini kweetyhubhu nangalo siyabaqalekisa abantu abenziwe kulo ukubonisa umsebenzi ebalulekileyo kwiminyaka engaphezu kwama-40.

kubuxhakaxhaka bokuvelisa

Ukulungiswa Polyvinyl chloride polymerization olukhulu ikhutshwa phandle izinto ekrwada, leyo isebenza IVinyl chloride. I lisetyenziswe kakhulu kushishino yaba yinkqubo oluludaka, oku kungenxa yokuba oko kunika ukusebenza eliphezulu. Loo polymerization lwenziwa kwinkqubo ngamaxesha athile. IVinyl chloride, nto leyo uqulathwe mali ka-0,02 - 0.05 pesenti kwixesha eliphakathi zolwelo Zisebenziselwa component ephambili. Le feedstock ukulungele lusitsha ukuze degrees 65, uze emva koko phantsi yempembelelo efanayo ukufumana imveliso eyohlobo olulodwa. Le polymerization ithatha indawo amathontsi of IVinyl chloride. Ekugqibeleni, abakwazi ukufumana microgranules misindo. Ukuveliswa nokuhambisa ngokupheleleyo, lo gama i-polymerization oluqhutywa zamandla ogama volume mkhulu kwama-200 cubic metres. Emva kokugqitywa weqondo polymerization of IVinyl chloride, nto leyo waphendula ngelo xesha, ukuya ku-90 ekhulwini. Izinto eziye ayisetyenziswa asuswe, lo gama PVC iya ohluzwe wome kunye nomoya oshushu. Emva koko kwenzeka ukuphakheja. PVC, iimpawu eziye ichazwe ngasentla, inyathelo lokugqibela iguqulelwa IVinyl nqanawa okanye iplastiki.

Iimveliso PVC lokugqibela

impahla PVC inokujikwa ibe IVinyl nqanawa. Yena yimveliso nzima. Lubonakala ngokuba amandla aphezulu ngomatshini, ukumelana ukuhlasela kwemichiza kunye manzi. Phakathi iintsilelo ukuba abahluphekileyo amandla impembelelo, ukumelana iqabaka abahluphekileyo okuncinane yokusebenza zisembundwini wawo. Ngokumalunga stiffener, kuba ukudla athambileyo ube luthambe ebalulekileyo. Kananjalo luphawulwa nokumelana ngamanzi kunye nokumelana oyile. Ukuba bangenele nempembelelo enkulu organic izinyibilikisi ezahlukeneyo.

isiphelo

PVC, imibhobho esuka kuyo bagqibileyo namhlanje, umi njengenye yezinto zixhaphakileyo kuquka iiplastiki. imveliso kwiHlabathi Jikelele lumalunga-17 pesenti Iyonke iimveliso zeplastiki, kwaye ubekwa kwindawo yesithathu phakathi neeplastikhi. Iimveliso ezenziwe PVC, wafumana isicelo eluncedo kumacandelo amaninzi kwezoqoqosho, kushishino, ubunjineli enzima, amayeza kunye nezolimo. Namhlanje, phantse zonke ndlu kufakwa iiwindow plastiki, kwakunye nemveliso ezisetyenziswa ngokusekelwe umbandela ochazwe. Oku kwande ibonisa iimpawu ezigqwesileyo esemgangathweni umbandela ngasentla eye amandla aphezulu, ukumelana umonakalo lwangaphandle kunye neempembelelo endalo ezahlukeneyo.
