Ukwenziwa kweplastiki yePVC
Ukwenziwa kwePVC yeplastiki,
I-PVC Resin, PVC resin kunye nesongezo, I-resin ye-PVC yokuvelisa umbhobho, I-PVC SG-5, I-PVC SG-8, I-PVS SG-7,
Ukuqulunqwa kwePVC yeplastiki kuqulunqwe ikakhuluPVC resin kunye nesongezos, ezongezo ezihambelana nomsebenzi zahlulwe zibe: ukuzinzisa ubushushu, i-lubricant, isilungisi sokulungisa, isilungisi sempembelelo, isigcwalisi, i-arhente yokuguga, umbala kunye nokunye.Ngaphambi kokuyila ukwakhiwa kwePVC, kufuneka siqale siqonde iimpawu zePVC resin kunye nezongezo ezahlukeneyo.
Imathiriyeli ekrwada kunye nezongezo
PVC intlaka
Ukuveliswa kweprofayili yeplastiki yePVC ye-resin yi-polyvinyl chloride resin (PVC), i-PVC yenziwe nge-vinyl chloride monomer polymerization polymer, imveliso yesibini kuphela kwi-PE, ibeka okwesibini.
I-resin ye-PVC inokohlulwa ibe yintlobo ekhululekileyo (XS) kunye nohlobo oluqinileyo (ⅺ) ngenxa yee-dispersants ezahlukeneyo kwi-polymerization.Ubungakanani besuntswana elixekethileyo yi-0.1-0.2mm, umphezulu awuqhelekanga, ubumdaka, ibhola yomqhaphu, kulula ukufunxa iplasticizer, ubungakanani bamasuntswana acwebileyo bungaphantsi kwe-0.1mm, imithetho yomphezulu, iqinile, imilo yentenetya yetafile, akukho lula ukufunxa iplasticizer, ukusetyenziswa kwangoku. yohlobo olukhululekileyo ngakumbi.
I-PVC inokohlulwa ibe yibakala eliqhelekileyo (i-PVC enetyhefu) kunye nebakala lezempilo '(i-PVC engeyiyo eyityhefu).Iimfuno zomgangatho wezempilo we-vinyl chloride (VC) umxholo ophantsi kune-LOXL0-6, ingasetyenziselwa ukutya kunye namayeza.Inkqubo yokwenziwa yahlukile, iPVC inokwahlulwa ibe yiPVC yokunqunyanyiswa kunye ne-emulsion yePVC.Ngokomgangatho wesizwe we-GB/T5761-93 "indlela yokunqunyanyiswa ngokubanzi i-polyvinyl chloride yokuhlola i-resin standard", indlela yokuxhoma i-PVC yahlulwe ibe yi-PVC-SGL ukuya kwi-PVC-SG8JK resin, elincinane inani, iqondo elikhulu lepolymerization, inkulu ubunzima bemolekyuli, kokukhona amandla aphezulu, kodwa okukhona kunzima ukunyibilika, ukusetyenzwa nako kunzima ngakumbi.Ukhetho oluthile, yenza iimveliso ezithambileyo, ukusetyenziswa ngokubanzi kwe-PVC-SGL, i-PVC-SG2, uhlobo lwe-PVC-SG3, kufuneka ukongeza inani elikhulu le-plasticizers.Ngokomzekelo, ifilimu ye-PVC isebenzisa i-resin ye-SG-2, yongeza i-50 ukuya kwi-80 ye-plasticizer.Kwaye xa ulungisa iimveliso ezinzima, musa ukongeza okanye ukongeza iplastiki kwixabiso elincinci kakhulu eliqhelekileyo, sebenzisa i-PVC-SG4, i-VC-SG5, i-PVC-SG6, i-PVC-SG7, i-PVC-SG8 ngoko.Njengombhobho onzima wePVC usebenzisa i-SG-4 resin, umnyango weplastiki kunye neeprofayili zefestile usebenzisa i-SG-5 resin, i-hard transparent sheet usebenzisa i-SG-6 resin, iiprofayili ze-foam ezinzima usebenzisa i-SG-7, i-SG-8 resin.Kwaye i-emulsion ye-PVC yokunamathisela isetyenziselwa kakhulu ngesikhumba sokwenziwa, iphepha lodonga kunye nomgangatho wesikhumba kunye neemveliso zeplastiki zediphu.Abanye abavelisi be-PVC be-resin ye-PVC ngokweqondo le-polymerization (iqondo le-polymerization linani leyunithi yekhonkco, iqondo le-polymerization liphindaphindwe ubunzima be-molecular of the chain lilingana nobunzima be-molecular ye-polymer) ukuhlelwa, njenge-Shandong Qilu petrochemical plant jikelele. ukuveliswa kwe-PVC resin, iimveliso zefektri ye-SK-700;SK - 800;SK - 1000;SK - 1100;I-SK - 1200, njl njl. Iqondo elihambelanayo le-polymerization ye-SG-5 resin yi-1000 - 1100. Iimpawu ezibonakalayo kunye neekhemikhali ze-PVC resin zibone okwesine.
I-PVC powder ngumgubo omhlophe kunye nobuninzi be-1.35 - 1.45 g / cm3 kunye nobuninzi obubonakalayo be-0.4-0.5 g / cm3.Hlola ubungakanani bomxholo we-plasticizer unokuba thambileyo, iimveliso ezinzima, umxholo we-plasticizer jikelele 0-5 yimveliso enzima, i-5-25 yimveliso enzima, ngaphezu kwe-25 yimveliso ethambileyo.
I-PVC luhlobo lwe-amorphous, i-polar ye-polar, ubushushu obuthambileyo kunye nobushushu obunyibilikayo buphezulu, i-PVC ecocekileyo ngokubanzi kufuneka ibe kwi-160-210 ~ C ukusetyenzwa kweplastiki, ngenxa yebhondi ye-polar phakathi kwe-macromolecules ukuze i-PVC ibonise ukusebenza okunzima kunye nokuphazamiseka.Ngaphezu koko, iimolekyuli ze-PVC eziqulethe amaqela e-chlorine, xa ubushushu bufikelela kwi-120 ~ C, i-PVC ecocekileyo iya kuqala ukususa ukuphendula kwe-HCl, iya kukhokelela ekuthotyweni kwe-thermal ye-PVC.Ke ngoko, zonke iintlobo zezongezo kufuneka zongezwe kwi-processing ye-PVC yokuguqulwa kunye nokuguqulwa kwempembelelo, ukwenzela ukuba iqhutywe ibe yimveliso eluncedo.
I-resin ye-PVC isetyenziselwa ukuveliswa kweentlobo ezahlukeneyo zefilimu ebhityileyo (ezifana nefilimu yoshicilelo yemihla ngemihla, ifilimu yokupakisha yemizi-mveliso, ifilimu yezolimo yegreenhouse, ifilimu eshwabeneyo yobushushu, njl.njl.), zonke iintlobo zepleyiti, iphepha, iphepha lingasetyenziselwa Iimveliso zamadyungudyungu), zonke iintlobo zemibhobho, njengengeyiyo ityhefu kumbhobho wokuthunga, umbhobho ocacileyo, njl.njl.), zonke iintlobo zezinto ezinokwakheka okukhethekileyo, njengomnyango, ifestile, ipleyiti yokuhombisa, ibhotile yokuvuthela engenanto (yezinto zokuthambisa kunye iziselo), Ikhebula, zonke iintlobo zeemveliso zokutofa kunye nesikhumba sokwenziwa, isikhumba somgangatho, iithoyi zeplastiki, njl.
IZibo Junhai Chemical yiarhente yokuqala yeSinopec Qilu, olona phawu luphambili lwePVC lulandelayo.
