Gushyira mu bikorwa hydroxyPropyl methyl Methiolose mu musaruro w'icyiciro kinini cya chloride ya polyviny

Abstract: Gushyira mu bikorwa byo mu rugohydroxypropyl methylcellseAho gutumiza mu mahanga umwanzuro wa PVC hamwe n'impamyabumenyi ndende ya polymeirileyation. Ingaruka zubwoko bubiri bwa hydroxypropyl methylcellse kumitungo ya PVC ifite impamyabumenyi ndende ya Polymeration. Ibisubizo byerekanaga ko byashobokaga gusimbuza hydroxypropyl methyl selile yatumije.

Urwego rwo hejuru-rwa-polymerations resins zerekeza kuri PVC isohoka hamwe ninzego zidasanzwe zamajwi zirenga 1.700 cyangwa hamwe nuburyo buhujwe gato hagati ya molekile, muribyo bikunze kugaragara muri PVC hamwe ninzego zisanzwe za polyérimeation ya 2,500 [1]. Ugereranije na PVC isanzwe ya PVC, hejuru-nyinshi cyane pvc iroboshya cyane, kwikuramo guto, kurwanya ubushyuhe, kurwanya ubushyuhe, kurwanya umunaniro hamwe no kwambara umunaniro. Numusimbura mwiza wa rubber kandi irashobora gukoreshwa mukangurana ry'imodoka, insinga n'amavugo, cabée, n'ibindi [2].

Uburyo bwo gutunganya bwa PVC hamwe nurwego rwo hejuru rwa polymeyetisi ni ubuhagarikwa cyane cyane guhagarikwa [3-4]. Mu gukora uburyo bwo guhagarika, abatatanye ni umukozi wingenzi ufasha, kandi ubwoko bwacyo kandi umubare wacyo bizagira ingaruka muburyo butandukanye, gukwirakwiza ibice bya PVC birangiye. Sisitemu ikwirakwizwa ikoreshwa ni sisitemu yo kunywa polyvinyl na hydroxypropyl methylcellse na polyvinyl inzoga zitatanya sisitemu, kandi abakora murugo bakoresha ahanini [5].

1 ibikoresho byibanze nibisobanuro

Ibikoresho by'ibanze n'ibisobanuro bikoreshwa mu kizamini bwerekanwa mu mbonerahamwe ya 1. Birashobora kugaragara ku mbonerahamwe ya 1 ko hydroxypropyl methylcellropyl methylcellse, itanga ibisabwa kugirango usimburwe muri ibi impapuro.

Ibizamini 2

2. 1 Gutegura HydroxyPropyl Methylcellse Igisubizo

Fata umubare runaka wamazi deiyoni, ubishyire muri kontineri no gushyushya kuri 70 ° C, hanyuma wongere buhoro buhoro ongera hydroxyPropyl methylcellse munsi yigihe cyo guhorana. Ubugari bureremba hejuru y'amazi mbere, hanyuma buhoro buhoro ukwirakwiza kugeza igihe kivanze. Gukonjesha igisubizo cyijwi.

Imbonerahamwe 1 ibikoresho nyamukuru nibisobanuro byabo

2. Uburyo 2 bwo Kwipimisha

Ku gikoresho cya 10 L. Koresha HydroxyPropyl Methyl Methyl Methiose kugirango asimbure HYdroxyPropyl Methyl Cellulose kugirango yipimisha; Ibicuruzwa bya PVC resin byakozwe na hydroxyproppopyl methyl methyl methyl yagereranijwe no kwiga uburyo bwo gusimbuza hydroxypropyle Dukurikije ibyavuye mu kizamini gito, ikizamini cyo gukora cyakozwe.

2. INTAMBWE 3

Mbere yo kugitwara, funga isakofuriya, funga valve yo hepfo, ongeraho umubare runaka wamazi aryamye, hanyuma wongere abatatanye; Funga umupfundikizo w'ikifu, kurakara nyuma yo gutsinda igitutu cya azote, hanyuma wongere vinomer ya vinyl; Nyuma yo gukonjesha, ongeraho uwatangiye; Koresha kuzenguruka amazi kugirango uzamure ubushyuhe mu isabukuru, hanyuma wongere igisubizo cya Ammonium mu gihe mugihe cyo guhindura agaciro ka sisitemu yigisubizo; Iyo umuvuduko wigisubizo ugabanuka ku gitutu cyerekanwe muri formula, ongeraho umukozi uhagarika umutima, kandi usohore ibicuruzwa byarangiye bya PVC byabonetse na centrifugari no kumisha, hanyuma ugatanga icyitegererezo.

2. Uburyo 4 Isesengura

Nk'uko uburyo bwo kwipimisha bujyanye na Enterprises Bisanzwe Q31 / 0116000823C002-2018, umubare wa sposity, ikibazo cya Plastices, kirimo ibintu bifatika bya PVC byarangiye kandi birasesengurwa; Impuzandengo ya PVC isigaye yageragejwe; Ikipe ya PVC igaragaramo ibice byagaragaye gukoresha microscope ya electron.

Ibisubizo 3 n'ibiganiro

Kanda 2. Ukurikije uburyo bwo kwipimisha bwasobanuwe muri 4, buri cyiciro gito cyarangije PVC kimaze kugeragezwa, kandi ibisubizo byerekanwe mu mbonerahamwe ya 2.

Imbonerahamwe 2 ibisubizo byibice bitandukanye byikizamini gito

Irashobora kugaragara ku mbonerahamwe ya 2: Ubwinshi bugaragara, nimero ya vistisi na plastisar yo muri resin yabonetse yabonetse ukoresheje selile zitandukanye kubizamini bito; Ibicuruzwa bya resin byabonetse ukoresheje hydroxypropyl methylcellse formulaire impuzandengo ugereranije ni ntoya.

Igishushanyo 1 cyerekana amashusho ya sem yibicuruzwa bya PVC byabonetse ukoresheje HydroxyProppopyl Methylcellse.

(1) -Ibikoresho bya hydroxypropyl methylcellse

(2)--KomerroxyPropyl methylcellse

Igishushanyo 1 Sem yinjira muri 10-l Polymerizer imbere ya HydroxyPropyl Methyl Cellulose

Birashobora kugaragara kuva ku gishushanyo cya 1 kugirango imiterere yo hejuru ya PVC isiga yakozwe na selile itandukanye ipasanwa zisa.

Kuri Guverinoma, birashobora kugaragara ko hydroxypropyl methylcellse muriyi mpapuro ifite uburyo bushoboka bwo gusimbuza hydroxypropyl methylcellepy.

3. 2 isesengura ryiza ryubwiza bwa PVC risohoka hamwe nimpamyabumenyi ndende ya Poly

Bitewe nigiciro kinini ningaruka zo kwipimisha umusaruro, gahunda yuzuye yo gusimbuza ikizamini gito ntishobora gukoreshwa mu buryo butaziguye. Kubwibyo, umugambi wo kwiyongera buhoro buhoro igice cya hydroxy ofs yo murugo Methylcellse muri formula yemejwe. Ibizamini bya buri ntebe byerekanwe mu mbonerahamwe ya 3. Yerekanwa.

Imbonerahamwe 3 Ibizamini Byibicuruzwa Bitandukanye

It can be seen from Table 3 that the usage of domestic hydroxypropyl methylcellulose was gradually increased until all batches of domestic hydroxypropyl methylcellulose replaced imported hydroxypropyl methylcellulose. Ibipimo ngenderwaho no kwinjiza plastisar kandi ubucucike bugaragara ntabwo bwahinduye cyane, byerekana ko hydroxypropyl methylcellropyl methylcellse mu musaruro.

UMWANZURO

Ikizamini cyo murugohydroxypropyl methyl selileKu gikoresho cya 10 l Ibikorwa byo gusimbuza ibizamini byerekana ko hydroxyproppopyl methyl umusaruro wa PVC, ibipimo ngenderwaho byingenzi bya PVC bisohoka muri PVC yarangiye kandi bitumizwa mu mahanga hythyl methyl methyl methyl methyl methyl methyl methyl methyl methyl methyl methyl methyl methyl methyl methyl Methyl Kugeza ubu, igiciro cya selile yo murugo ku isoko kiri munsi kurenza iyo selile yatumije. Kubwibyo, niba selile yo murugo ikoreshwa mugukora, ikiguzi cya sida yumusaruro kirashobora kugabanuka cyane.
