PVC resin isetyenziswa ngokubanzi kumashishini ahlukeneyo.Ngokwenqanaba le-polymerization ye-PVC resin, ubunzima bayo bukwahlukile.
Iprofayile yePVC
Iprofayili kunye neprofayili yimimandla esetyenziswa kakhulu kwi-PVC e-China, ibalwa malunga ne-25% yokusetyenziswa okupheleleyo kwePVC.Zisetyenziswa ikakhulu ukwenza iingcango kunye neefestile kunye nezixhobo zokonga amandla.Isicelo sabo sisakhula ngomda omkhulu kulo lonke ilizwe.Kumazwe ahambele phambili kwezoqoqosho, isabelo semarike yeengcango zeplastiki kunye neefestile sesona siphezulu, njenge-50% eJamani, i-56% eFransi kunye ne-45% e-United States.
Umbhobho wePVC
Phakathi kweemveliso ezininzi ze-PVC, umbhobho we-PVC yintsimi yesibini enkulu yokusetyenziswa, ibalwa malunga ne-20% yokusetyenziswa kwayo.E-China, umbhobho we-PVC uphuhliswa kwangaphambili kunombhobho we-PE kunye nombhobho we-PP, kunye neentlobo ezininzi, ukusebenza okugqwesileyo kunye noluhlu olubanzi lwesicelo, oluthatha indawo ebalulekileyo kwimarike.
PVC inwebu
Ukusetyenziswa kwe-PVC kwintsimi ye-membrane ye-PVC ithatha indawo yesithathu, ibalwa malunga ne-10%.Emva kokuba i-PVC ixutywe kwaye ifakwe iplastiki kunye nezongezo, ifilimu ecacileyo okanye enemibala enobunzima obuchaziweyo yenziwe nge-roll ezintathu okanye ezine-calender roll.Ifilimu icutshungulwa ngale ndlela ukuze ibe yifilimu yekhalenda.Unako kwakhona ukusika kunye nobushushu ukupakisha iingxowa zokupakisha, ii-raincoats, amalaphu etafile, amalengalenga, iithoyi inflatable, etc. Ifilimu elubala ngokubanzi ingasetyenziselwa greenhouse, greenhouse yeplastiki kunye nefilimu yeplastiki.Ifilimu eyoluliweyo ye-biaxially ineempawu ze-thermal shrinkage kwaye ingasetyenziselwa ukupakishwa kwe-shrinkage.
PVC izinto ezinzima kunye neepleyiti
I-PVC yongezwa nge-stabilizer, i-lubricant kunye ne-filler.Emva kokuxuba, imibhobho enzima, imibhobho ekhethekileyo kunye nemibhobho edibeneyo yobubanzi obuhlukeneyo inokukhutshwa nge-extruder ye-downcomer, ipayipi yamanzi okusela, i-wire sleeve okanye i-stair handrail.Amaphepha e-calender anokuthi agqitywe kwaye ashushu acinezele ukwenza iipleyiti ezinzima ezinobunzima obahlukeneyo.Ipleyiti inokusikwa kwimilo efunekayo, kwaye emva koko idityaniswe kwiitanki zokugcina ezikwazi ukumelana nemichiza, imibhobho yomoya kunye nezikhongozeli ezinePVC yombane kunye nomoya oshushu.
PVC iimveliso ezithambileyo jikelele
Inokukhutshelwa kwimibhobho, iintambo, iingcingo, njl. nge-extruder;Iimbadada zeplastiki, i-soles, i-slippers, amathoyizi, iinxalenye ze-auto, njl.
PVC ukupakisha izinto
Iimveliso zePVC zisetyenziselwa ukupakisha izikhongozeli ezahlukeneyo, iifilimu kunye namaqhekeza anzima.Izikhongozeli zePVC ikakhulu zivelisa amanzi amaminerali, isiselo kunye neebhotile zokuthambisa, kwaye zikwasetyenziselwa ukupakishwa kweoyile esulungekileyo.Ifilimu ye-PVC ingasetyenziselwa i-CO extrusion kunye nezinye iipolymers ukuvelisa iimveliso ze-laminated ezinexabiso eliphantsi kunye neemveliso ezicacileyo ezinomqobo olungileyo.Ifilimu yePVC ingasetyenziselwa ukolula okanye ukupakishwa okushwabeneyo kobushushu, kunye nokupakisha oomatrasi, ilaphu, izinto zokudlala kunye nemveliso yamashishini.
Iiphaneli zodonga zePVC kunye nemigangatho
Iiphaneli zodonga ze-Pvc zisetyenziswa ikakhulu ukutshintsha iipaneli zodonga lwe-aluminium.Ukongeza kwinxalenye ye-PVC ye-resin, amanye amacandelo eethayile zomgangatho we-PVC zizinto ezisetyenzisiweyo, izinto zokuncamathelisa, izihluzi kunye namanye amacandelo, asetyenziswa ikakhulu kumhlaba wesakhiwo sesikhululo seenqwelomoya kunye nomhlaba oqinileyo kwezinye iindawo.
PVC iimpahla zabathengi
Ingxowa yemithwalo yimveliso yemveli eyenziwe ngePVC.I-PVC isetyenziselwa ukwenza zonke iintlobo zesikhumba sokuxelisa, ingxowa yemithwalo kunye neemveliso zemidlalo, ezifana nebhola yomnyazi, ibhola kunye nebhola.Ingasetyenziselwa ukwenza iyunifomu kunye neebhanti zezixhobo ezikhethekileyo zokukhusela.Amalaphu e-PVC empahla adla ngokufunxa amalaphu (ngaphandle kokutyabeka), njengeeponcho, ibhulukhwe yomntwana, iibhatyi zesikhumba ezixelisayo kunye neebhutsi zemvula ezahlukeneyo.I-Polyvinyl chloride isetyenziswa kwimidlalo emininzi kunye neemveliso zokuzonwabisa, ezifana namathoyizi, iirekhodi kunye nempahla yezemidlalo.Iithoyi zePolyvinyl chloride kunye neempahla zemidlalo zinokukhula okukhulu.Inenzuzo ngenxa yeendleko zayo eziphantsi zokuvelisa kunye nokubumba okulula.
Iimveliso ezigqunywe ngePVC
Isikhumba sokwenziwa ngesubstrate yenziwa ngokugalela iPVC elaphuni okanye ephepheni kwaye iplastiki ibekwe ngaphezu kwe-100 ℃.I-PVC kunye nezongezelelo nazo zinokufakwa kwi-calender kwifilimu, kwaye emva koko zicinezelwe nge-substrate.Isikhumba sokwenziwa ngaphandle kwe-substrate ifakwe ngokuthe ngqo kwi-calenders kwi-soft sheets yobunzima obuthile nge-calender, kwaye emva koko icinezelwe ngeepatheni.Isikhumba sokwenziwa sinokusetyenziswa ukwenza iisutikheyisi, iibhegi, izigqubuthelo zeencwadi, iisofa kunye nemiqamelo yemoto, kunye nesikhumba esisezantsi, esinokusetyenziswa njengezinto zokugalela izakhiwo.
Iimveliso zogwebu zePVC
Xa i-PVC ethambileyo ixutywe, isixa esifanelekileyo se-arhente yogwebu yongezwa kwiphepha ukwenza iplastiki yogwebu, enokusetyenziswa njenge-slippers yogwebu, iimbadada, ii-insoles, kunye nezixhobo zokupakisha zokupakisha.Isenokwenziwa kwakhona kwiipleyiti zePVC ezivuthuza amagwebu eziphantsi kunye neeprofayili ezisekelwe kwi-extruder, ezinokuthatha indawo yomthi.Sisixhobo esitsha sokwakha.
Iphepha elicacileyo lePVC
I-PVC ixutywe, yenziwe ngeplastiki kwaye ifakwe kwi-calender kwi-transparent sheet ngokongeza isilungisi sempembelelo kunye ne-organotin stabilizer.I-Thermoforming ingasetyenziselwa ukwenza izikhongozeli ezicacileyo ezinodonga olucekethekileyo okanye ukupakishwa kwe-vacuum blister.Yimpahla egqwesileyo yokupakisha kunye nempahla yokuhlobisa.
Abanye
Iingcango kunye neefestile zidityaniswe ngezixhobo eziqinileyo ezinokwakheka okukhethekileyo.Kwamanye amazwe, iye yahlala kwimarike yeengcango kunye neefestile kunye neengcango zeplanga, iifestile kunye neefestile ze-aluminium;Ukuxelisa izinto zokhuni kunye nezinto zokwakha zentsimbi (eNyakatho kunye nolwandle);Isikhongozeli esingenanto.
Isekethe ye-Virtual yenye yeenkonzo ezinikezelwa yi-packet switching network (enye yinkonzo yedathagram).Ngamafutshane, kukuseka uqhagamshelo olunengqiqo phakathi kwenginginya zabasebenzisi ngokusebenzisa indlela yolawulo lwangaphakathi yenethiwekhi, kunye nokuqinisekisa ukuchaneka kunye nokulandelelana kokuhambisa iipakethi kuyo.Isekethe ebonakalayo kufuneka isekwe kwaye isuswe ngaphambi nangemva konxibelelwano.Isekethe yenyani esisigxina yisekethe ebonakalayo esekwe ngexesha lokuqaliswa kwenethiwekhi, kwaye isekethe ebonakalayo igcinwa ngalo lonke ixesha.
