Ibisobanuro:Hakozwe ubushakashatsi ku ngaruka zitandukanye za hydroxypropyl methylcellulose ether ku miterere ya minisiteri isanzwe yumye ivanze na pompe. Ibisubizo byerekanaga ko: hamwe no kwiyongera kwibirimo bya selile ya ether, ubudahangarwa nubucucike byagabanutse, kandi igihe cyo gushiraho cyaragabanutse. Kwiyongera, 7d na 28d imbaraga zo kwikuramo byagabanutse, ariko muri rusange imikorere ya minisiteri yumye ivanze yaratejwe imbere.
0.Ijambo ry'ibanze
Mu 2007, minisiteri na komisiyo esheshatu z’igihugu byasohoye “Itangazo ryo kubuza kuvanga Mortar ku mbuga zimwe na zimwe mu gihe runaka”. Kugeza ubu, imijyi 127 yo mu gihugu yakoze imirimo yo “kubuza minisiteri iriho”, yazanye iterambere ritigeze ribaho mu iterambere rya minisiteri ivanze. amahirwe. Hamwe niterambere rikomeye rya minisiteri ivanze yumye kumasoko yubwubatsi bwimbere mu gihugu ndetse n’amahanga, imiti itandukanye ivanze na minisiteri yumye nayo yinjiye muri uru ruganda rugenda rwiyongera, ariko bimwe mubicuruzwa bivangwa na minisiteri hamwe n’amasosiyete agurisha bikabije nkana umusaruro wibicuruzwa byabo, bikayobya byumye- inganda zivanze. iterambere ryiza kandi rifite gahunda. Kugeza ubu, nkibintu bifatika bifatika, byumye-bivanze na minisiteri ikoreshwa cyane cyane hamwe, kandi ugereranije ni bike bikoreshwa wenyine. By'umwihariko, hari ubwoko bwinshi bwimvange mubintu bimwe na bimwe bikora byumye bivangwa na minisiteri, ariko Mubisanzwe bisanzwe byumye bivanze, ntabwo bikenewe gukurikirana umubare wibyongeweho, ariko hakwiye kwitabwaho cyane kubikorwa byacyo no gukora, kugeza irinde gukoresha cyane imiti ya minisiteri, itera imyanda idakenewe, ndetse bigira ingaruka kumiterere yumushinga. Mubisanzwe byumye bivanze, selile ether igira uruhare mukubika amazi, kubyimba, no kunoza imikorere yubwubatsi. Imikorere myiza yo gufata neza amazi yemeza ko minisiteri ivanze yumye itazatera umusenyi, ifu no kugabanuka kwingufu kubera kubura amazi hamwe na sima ituzuye; ingaruka zo kubyimba byongera cyane imbaraga zimiterere ya minisiteri itose. Uru rupapuro rukora ubushakashatsi bufatika ku ikoreshwa rya selile ya selile muri minisiteri isanzwe yumye ivanze, ifite akamaro kayobora uburyo bwo gukoresha ibivanze neza muburyo busanzwe bwumye buvanze.
1. Ibikoresho bito nuburyo bukoreshwa mugupimisha
1.1 Ibikoresho bito byo gukora ikizamini
Isima yari p. ubucuruzi buboneka hydroxypropyl methyl selulose ether (viscosity 12000 MPa · s).
1.2 Uburyo bwo kugerageza
Icyitegererezo cyo gutegura no gupima imikorere cyakozwe hakurikijwe JCJ / T 70-2009 uburyo bwibanze bwibizamini byo kubaka minisiteri.
2. Gahunda yikizamini
2.1 Inzira yikizamini
Muri iki kizamini, ingano ya buri kintu kibisi cya toni 1 ya pompe yumye ivanze yumye ikoreshwa nkuburyo bwibanze bwo kwipimisha, kandi amazi nugukoresha amazi ya toni 1 ya minisiteri ivanze.
2.2 Gahunda yihariye
Ukoresheje iyi formula, ingano ya hydroxypropyl methylcellulose ether yongewe kuri buri toni ya minisiteri ivanze ivanze ni: 0.0 kg / t, 0.1 kg / t, 0.2 kg / t, 0.3 kg / t, 0.4 kg / tt, 0,6 kg / t, kwiga ingaruka zingero zinyuranye za hydroxypropyl methylcellulose ether mukubika amazi, guhoraho, ubucucike bugaragara, kugena igihe, nimbaraga zo kwikomeretsa zisanzwe zumye zivanze zumye. minisiteri, kugirango iyobore ivangwa ryumye-ivanze neza Gukoresha neza imvange ya minisiteri irashobora kumenya neza ibyiza byumusaruro woroheje wivanze wa minisiteri, kubaka byoroshye, kurengera ibidukikije no kuzigama ingufu.
3. Ibisubizo by'ibizamini no gusesengura
3.1 Ibisubizo by'ibizamini
Ingaruka zingero zinyuranye za hydroxypropyl methylcellulose ether mukubika amazi, guhoraho, ubucucike bugaragara, kugena igihe, nimbaraga zo kwikuramo imbaraga zisanzwe zumye zivanze na pompe.
3.2 Isesengura ryibisubizo
Irashobora kugaragara uhereye ku ngaruka za dosiye zitandukanye za hydroxypropyl methylcellulose ether ku kugumana amazi, guhoraho, ubwinshi bugaragara, kugena igihe, nimbaraga zo kwikuramo imbaraga zisanzwe zumye zivanze na pompe. Hamwe no kwiyongera kwa selile ya selile, igipimo cyo gufata amazi ya minisiteri itose nacyo kigenda cyiyongera buhoro buhoro, kuva kuri 86.2% mugihe hydroxypropyl methyl selulose itavanze, kugeza kuri 0,6% mugihe hydroxypropyl methyl selulose ivanze. Igipimo cyo gufata amazi kigera kuri 96.3%, ibyo bikaba byerekana ko ingaruka zo gufata amazi ya propyl methyl selulose ether ari nziza cyane; ubudahwema bugabanuka buhoro buhoro bitewe ningaruka zo gufata amazi ya propyl methyl selulose ether (gukoresha amazi kuri toni ya minisiteri ntigihinduka mugihe cyubushakashatsi); Ubucucike bugaragara bwerekana inzira igabanuka, byerekana ko ingaruka zo gufata amazi ya propyl methyl selulose ether yongerera ubwinshi bwa minisiteri itose kandi ikagabanya ubucucike; igihe cyo gushiraho kigenda cyiyongera buhoro buhoro hamwe no kwiyongera kwa hydroxypropyl methyl selulose ether, nibiri muri Iyo bigeze kuri 0.4%, ndetse birenze agaciro kateganijwe ka 8h gasabwa nibisanzwe, byerekana ko gukoresha neza hydroxypropyl methylcellulose ether ifite ingaruka nziza yo kugenzura igihe cyo gukora cya minisiteri itose; imbaraga zo kwikuramo 7d na 28d zaragabanutse (Iyo dosiye nini, niko kugabanuka kugaragara). Ibi bifitanye isano no kwiyongera k'ubunini bwa minisiteri no kugabanuka k'ubucucike bugaragara. Kwiyongera kwa hydroxypropyl methyl selulose ether birashobora gukora umwobo ufunze imbere ya minisiteri ikomye mugihe cyo gushiraho no gukomera kwa minisiteri. Micropores itezimbere uburebure bwa minisiteri.
4. Icyitonderwa cyo gukoresha selile ya selile muri minisiteri isanzwe yumye-ivanze
1) Guhitamo ibicuruzwa bya selile. Muri rusange, uko ubwinshi bwa selulose ether, niko bigira ingaruka nziza yo gufata amazi, ariko uko ubukonje bwiyongera, niko kugabanuka kwayo, ibyo bikaba byangiza imbaraga nubwubatsi bwa minisiteri; ubwiza bwa selulose ether ni mike ugereranije na minisiteri yumye. Bavuga ko aribyiza, byoroshye gushonga. Munsi ya dosiye imwe, nibyiza, nibyiza byo gufata amazi.
2) Guhitamo selile ya selile. Duhereye ku bisubizo by'ibizamini no gusesengura ingaruka z'ibigize selulose ether ku mikorere ya minisiteri yumye ivanze na pompe, birashobora kugaragara ko uko ibintu byinshi biri muri selile ya selile, ari byiza, bigomba gutekerezwa uhereye ku giciro cy'umusaruro, ubuziranenge bwibicuruzwa, imikorere yubwubatsi nibintu bine byubwubatsi kugirango uhitemo neza dosiye ikwiye. Igipimo cya hydroxypropyl methyl selulose ether muri minisiteri isanzwe ivanze ivanze ni byiza 0.1 kg / t-0.3 kg / t, kandi ingaruka zo gufata amazi ntizishobora kuzuza ibisabwa bisanzwe niba umubare wa hydroxypropyl methyl selulose ether wongeyeho muke. Impanuka nziza; igipimo cya hydroxypropyl methyl selulose ether muri minisiteri idasanzwe idashobora kwangirika ni nka kg 3 / t.
3) Gukoresha selulose ether mubisanzwe byumye-bivanze. Muburyo bwo gutegura minisiteri isanzwe ivanze, hashobora kongerwamo urugero rukwiye rwo kuvanga, byaba byiza hamwe no gufata amazi hamwe ningaruka zibyibushye, kugirango bishobore gukora ingaruka ziterwa na superulose ether, kugabanya ibiciro byumusaruro, no kuzigama umutungo ; niba ikoreshwa wenyine Kuri selulose ether, imbaraga zo guhuza ntizishobora kuzuza ibisabwa, kandi ingano ikwiye ya pisitori ya latx ishobora kwongerwaho; kubera ubwinshi bwimvange ya minisiteri, ikosa ryo gupimisha ni rinini iyo rikoreshejwe wenyine. Ubwiza bwibicuruzwa bya minisiteri yumye.
5. Imyanzuro n'ibitekerezo
1) Muri minisiteri isanzwe yumye ivanze, hamwe no kwiyongera kwa hydroxypropyl methylcellulose ether, igipimo cyo gufata amazi gishobora kugera kuri 96.3%, ubwuzuzanye nubucucike buragabanuka, kandi igihe cyo kugena kikaba kirekire. Imbaraga zo kwikuramo za 28d zaragabanutse, ariko muri rusange imikorere ya minisiteri ivanze yumye yarushijeho kunozwa mugihe ibikubiye muri hydroxypropyl methyl selulose ether byari biciriritse.
) Bitewe numubare muke wa minisiteri, ikosa ryo gupimisha ni rinini iyo rikoreshejwe wenyine. Birasabwa kubivanga nuwabitwaye mbere, hanyuma ukongera umubare winyongera kugirango ubuziranenge bwibicuruzwa bivangwa na minisiteri yumye.
3) Imashini ivanze yumye ninganda zigaragara mubushinwa. Muburyo bwo gukoresha imiti ivangwa na minisiteri, ntitugomba gukurikirana buhumyi ingano, ahubwo tugomba kwita cyane kubuziranenge no kugabanya ibiciro byumusaruro, gushishikariza gukoresha ibisigazwa by’inganda, kandi rwose tugera ku kuzigama ingufu no kugabanya ibicuruzwa.
