Abstract: Iko kushandiswa kweimbahydroxypruppropyl methylcellosePanzvimbo pekutorwa kunze kwekugadzirwa kwePVC ine yakakwirira polymeration degree yakaunzwa. Mhedzisiro yemhando mbiri dze hydroxyprupyl methylcellose pane zvivakwa zvePVC ine yakakwirira polymeration degree yakafemerwa. Mhedzisiro yacho yakaratidza kuti yaisanganisira kutsiva hydroxyprishropropropyl methyl cellelose yekune imwe kunze kwenyika.
Yakakwira-degree-ye-Polymerization PVC respins nePVC Mahara yePolymerization yeanopfuura mamorekukwana [1]. Kuenzaniswa neyakajairwa PVC Resin, Highmerization PHVC Resin ine kusimba kukuru, kuwirirana zvidiki zvakaiswa, kupokana kwakanaka, kuchembera kupokana, kuparara kupokana nekupfeka kupokana. Icho chakakodzera rubber chinotsiva uye chinogona kushandiswa mumotokari inosimbisa yemotokari, waya uye tambo, machirisi ekurapa, nezvimwe.
Iyo nzira yekugadzira yePVC ine yakakwirira degree yePolymerization inonyanya kumiswa polymerization [3-4]. Mukugadzirwa kwenzira yekumiswa, iyo inopinza ndeye yakakosha mumiririri, uye mhando yayo uye huwandu hwayo huchakanganisa zvakananga chimiro chemuviri, chibatiso chakagoverwa, uye plasticlezer yekunyora kwePVC yakapera PVC resin. Iyo inowanzoshandiswa kupararira masisitimu ndeye polyvinyl methese uye hydroxyprupyl methylcellose uye polyvinyl doro rakavhiringidza masisitimu, uye vagadziri vepamba vanonyanya kushandisa iyo yekupedzisira [5].

2. 2 nzira yekuedzwa
Pane imwe 10 L Diki bvunzo mudziyo, shandisa kunze kwenyika hydroxypropyl methyl cellelose kuitisa bvunzo dzekuita kuti uone iyo yekutanga mafomu eyedzo. use domestic hydroxypropyl methyl cellulose to replace imported hydroxypropyl methyl cellulose for testing; The PVC resin products produced by different hydroxypropyl methyl cellulose were compared to study the replacement feasibility of domestic hydroxypropyl methyl cellulose. Maererano nemhedzisiro yebvunzo diki, bvunzo yekugadzira inoitwa.
2. 3 matanho matatu
Pamberi pekuita, geza iyo polmerization kettle, vhara vharuvhu repasi, wedzera imwe mvura yemvura, wobva wawedzera iyo yakavharika; Vhara chivharo che kettle, vacuumize mushure mekupfuura nitrogen yekudzivirira bvunzo, uye wozowedzera vinyl chloride monomer; Mushure mekutonhora kusimudzira, wedzera iyo Intator; Shandisa kutenderera kwemvura kusimudza tembiricha muKettle kuenda kuChicle Tembiricha, uye Wedzera Ammonium Bicarbonate Solution mumamiriro ezvinhu panguva iyi kugadzirisa iyo ph kukosha kweiyo nzira yekuita. Kana kudzvinyirira kwekudzvanywa kudonhedza kumanikidza kwakatarwa mufomula, wedzera mumiririri wekupedza uye kusimuka kwechigadzirwa chakapera, uye chigadzirwa chakapera
2. 4 Ongororo nzira
Sekureva kwenzira dzakakodzera dzekubvunzwa muBecprise Standard Q31 / 011600082-2018, Kuverengeka Kwevasiri, Kusanganisira mvura yekunyora kwezana 100 GPC Resin Iyo avhareji yehukuru hwePVC resin yakaedzwa; Iyo morphology yePVC resin zvimedu zvakacherechedzwa uchishandisa leadron elektroncope.

Inogona kuoneka kubva kuTafura 3 iyo yekushandisa yeiyo hydroxpropropyl Zviratidzo zvikuru zvakadai sekunyora kweplasticze uye kuoneka kwekushandura zvakanyanya, zvichiratidza kuti hydroxproproproproproprollose yakasarudzwa mupepa rinogona kutsiva iyo hydroxproproproproproprollulose mukugadzira.
4 Mhedziso
Muedzo weimbahydroxypruppyl methyl cellulosePane imwe 10 L Diki bvunzo yebvunzo inoratidza kuti ine hutano hwekutsiva kunze kwenyika hydroxpropropropropropropyl methyl cellelose; Iyo yekudhinda yekutsiva inowana mitaxypressicPropropyl methyl methyl celleryl celler Parizvino, mutengo wemutengo weimba yemusha uri mumusika wakaderera pane iyo yekubvisa mari yekunze cellulose. Naizvozvo, kana cellertic merullose ichishandiswa mukugadzirwa, mutengo wezvinhu zvekugadzira AIDS zvinogona kuderedzwa zvakanyanya.
