I-Abstract: Ukusetyenziswa kwekhayahydroxypropyl methylcelceluploseEndaweni yokuthumela enye kwimveliso ye-PVC enenqanaba le-polymerizarazazation ephezulu. Iziphumo zentlobo ezimbini ze-hydroxypropyl methylceluplose kwipropathi yePVC enenqanaba le-polymerizazazation ephezulu laphandwa. Iziphumo zibonise ukuba kuyenzeka ukuba kuthathelwe indawo yokuhlala i-Hydroxyl ye-Methyl ye-metyl sellied yenye.
Inqanaba eliphezulu-le-Polymerization PVC libhekisa kwi-PVC i-Permerins enesidanga se-polymering engaphezulu kwe-1,700 okanye i-PVC edityanisiweyo ye-PVC iphinda isebenze nge-2,500 [1]. Xa kuthelekiswa ne-PVC eqhelekileyo ye-PVC, i-Polymerization ye-PERCIN ephezulu inesimo esiphezulu, ukunyanzelwa kobushushu, ukumelana nobushushu, ukumelana nobushushu, ukumelana nokungakhathali nokunganyangeki. Yinto efanelekileyo yerabha kwaye inokusetyenziswa kwimitya yokutywina yemoto, iingcingo kunye neentambo, abakhweli kwezonyango, njl. Njl.
Indlela yemveliso ye-PVC enenqanaba eliphezulu le-polymerizazazazazazazation ikakhulu kukumiswa kwePolymeris [3-4]. Kwimveliso yendlela yokumiswa, ukusasazeka yiarhente ebalulekileyo, kwaye uhlobo lwayo kunye nemali iya kuchaphazela ngokuthe ngqo ubume bethafa, ubungakanani be-suricle, kunye ne-plasticle ye-plastic ye-PVC Retin. Iinkqubo eziqhelekileyo zokusasazeka ziinkqubo ze-polyvinyl ze-pulyvinyl kunye ne-hydroxypropyl methylcelgalose ne-polyvinyl yotywala yokusasaza, kunye nabavelisi basekhaya basebenzise kakhulu le yokugqibela.
I-1 ephambili kunye neenkcazo
Ezona zinto ziphambili zoluhlaza kunye neenkcazo ezisetyenzisiweyo kuvavanyo ziboniswa kwiTheyibhile 1. Ingabonwa kwiTheyibhile 1 ukuba i-Hydropyl ye-Hydylcelcel ye-Hydylcelcelsulose inyulu ye-Hydylcelose yeli phepha.
2 Umxholo wovavanyo
2. 1 Ukulungiswa kwe-hydroxypropyl methylcelcelse
Thatha inani elithile lamanzi e-deeeed, yibeke kwisitya kwaye usitshise ukuya kwi-70 ° C, kwaye ngokuthe ngcembe yongeza i-HydroxlCHLELLE. I-selsulose idada emanzini ekuqaleni, kwaye emva koko ihlaselwe ngokuthe ngcembe ihlukile. Pholisa isisombululo kwivolumu.

2. 2 Indlela yovavanyo
Kwisixhobo sovavanyo esincinci se-10 le-10, sebenzisa i-hydroxypropyl ye-hythyl seluplose yokuqhuba iimvavanyo zeBenchmark ukumisela ifomula yesiseko yovavanyo oluncinci; Sebenzisa i-Hydroxypropyl ye-Hydropyl Methyl Selelise ukutshintsha i-hydroxyll ye-hydyl ye-methyl ye-methyl yesifo seseti; Iimveliso ze-PVC Retin eziveliswa yi-hydropyl ye-hydyl sellyulose ithelekiswa nokufunda ukutshintshwa kokufakwa endaweni ye-Hydroplopy ye-Hydyl. Ngokweziphumo zovavanyo oluncinci, uvavanyo lwemveliso lwenziwa.
2. Amanyathelo ama-3
Phambi kokuba aphendule, acoce i-celymerizarazazazarazazazarazazazation, vala ivalve esezantsi, Yongeza isixa esithile samanzi aselekelelwe, emva koko wongeze abasasazi; Vala isivalo seketile, phumla emva kokuphumelela uvavanyo loxinzelelo lwe-nitrogen, kwaye wongeza i-vinyl chloride momer; emva kokuvuselela okubandayo, yongeza umqalisi; Sebenzisa amanzi ajikeleze amanzi ukuphakamisa iqondo lobushushu kwiketile ukuya kwi-careed kwi-ampicalbonate isisombululo ngexesha elifanelekileyo ngeli thuba lokulungelelanisa ixabiso le-pH inkqubo; Xa uxinzelelo lokuphendula lwehlisa ukuya kwifomula echazwe kwifomula, yongeza iarhente yokuphelisa kunye nearhente yokuphelisa, kwaye ikhuphe imveliso egqityiweyo ye-PVC kwaye yomile, kunye nesampulu yohlalutyo.
2. Iindlela zokuhlalutyo
Ngokweendlela ezifanelekileyo zovavanyo kwi-q3 / 011660008233, inqaku le-viscosity, kubandakanya amanzi) kunye ne-Pronatiber (kubandakanya amanzi) ehlolwe i-PVC ivavanywa kwaye ahlalutywa; Ubungakanani obuqhelekileyo be-PVC Retin bavavanywa; I-morphology ye-PVC Persinsuns zaqwalaselwa kusetyenziswa i-scanscope ye-scann.
Iziphumo ezi-3 kunye nengxoxo

Ingabonwa kwiTheyibhile 2: Inombolo ebonakalayo, inombolo ye-viscosity kunye ne-plastiction Andssin ye-PVC ivale i-PVC isondele ngokusebenzisa i-selsulose eyahlukileyo yovavanyo oluncinci; Imveliso ye-resin ifunyenwe ngokusebenzisa i-Hydroxyll ye-Hydylcelcelgalose ifomula i-avareji ubungakanani bukhulu kakhulu.
Umzobo 1 ubonakalisa imifanekiso ye-SM ye-PVC yemveliso efunyenwe ngokusebenzisa eyahlukileyo ye-hydropylcellultulose.
(1) -Unyuswe i-hydroxypropyl methylcelcelceluplose
(2) -USomestic hydroxypropyl methylcelcelce
Ikhiwane. I-1 sem ye-resins eveliswe kwi-10-l polymerizer phambi kobukho be-hydropyl ye-hydyl sellise
Ingabonwa kumzobo 1 ukuba izakhiwo zomphezulu ze-PVC Retinsunsunts eziveliswa ngabasasazi abahlukeneyo baseSeleselie zifana.
Ukuzama ukuphakama, kunokubonwa ukuba i-HydroxyPyl ye-Hydropylcelcelcealsulose ihlolwe kweli phepha kunento enokwenzeka yokutshintsha indawo engeniswayo ye-Hydropylcelsele.
3. 2 Uhlalutyo lokuthelekisa lomgangatho we-PVC ngomgangatho ophezulu we-polymerizaration kuvavanyo lwemveliso
Ngenxa yeendleko eziphezulu kunye nomngcipheko wovavanyo lwemveliso, inkqubo epheleleyo yokutshintshwa kovavanyo oluncinci ayinakusetyenziswa ngokuthe ngqo. Ke ngoko, le nkqubo yokuqhekeka ngokuthe ngcembe ukwandisa umlinganiso we-Hydroxyll ye-Hydylceluplose kwifomula yamkelwa. Iziphumo zovavanyo zebhetshi nganye zibonisiwe kwiTheyibhile 3. Ibonisiwe.

Ingabonwa kwiTheyibhile 3 ukuba ukusetyenziswa kwe-Hydropyll ye-Hydylcelcelose inyuke ngokuthe ngcembe kude kube zonke iibatzylpyl methropyl Ezona zimpawu ziphambili zinjengobumbano lweplastiki kunye nokubonakala okungafunekiyo akuzange kuguquke ngokobukhali i-Hydropyll ye-HydylcelcelUlose ekuthatheni i-MydropylCose kwimveliso.
4 ISIQINISEKISO
Uvavanyo lwasekhayahydroxypropyl methyl seluploseKwisixhobo sovavanyo esincinci se-10 le-10 sibonisa ukuba kunokwenzeka ukuba ifake into yokutshintsha i-Hydroxyl ye-methyl ye-methyl sellulose; Iziphumo zovavanyo lwemveliso zibonisa ukuba i-Hydropyl ye-Hydyl ye-Methyl Selelin isetyenziselwa ukuveliswa kwe-PVC, eyona nto iphambili ye-PVC egqityiweyo ye-PVC kunye ne-hydroxlypropyl methyl sellulose. Okwangoku, ixabiso leselsese yasekhaya kwimarike iphantsi kuneyona iSeluplose ingeniswa elizweni. Ke ngoko, ukuba isellulose yasekhaya isetyenziswa kwimveliso, iindleko zokunqongophala zinokuncitshiswa kakhulu.
