I-VPMMSIT YOPHANDO I-HPMC: I-HPMC 400 isetyenziselwa ukuzibandakanya nodaka, kodwa ingeniswa ngokubanzi.
Isizathu: Ukugcinwa kwamanzi kuphantsi, nangona ukugcinwa kwamanzi kulihlwempu, kodwa amanqanaba okulungile, kwaye ukungcungcutheka kobungqingqwa kuphezulu.
I-vissium ephantsi kunye nePhazulu:hydroxypropyl methylcelceluploseI-HPMC 2000020000 isetyenziselwa ikakhulu i-Tile, iarhente ye-caulking, i-anti-cracking farr, i-interm yokufakelwa komsindo, njl.
Isizathu: Ukusebenza okuhle, ukuvunywa kwamanzi amancinci, ukungcola okuphezulu kwendalo.
1. Yeyiphi eyona njongo ye-hydroxypropyl methylcelcellulose (i-HPMC)?
-I-HPMC isetyenziswe ngokubanzi kwizinto zokwakha, iingubo, i-reomatis, i-ceramic, i-ceramics, iyeza, izibalo, iicusmetics, amanye amashishini. I-HPMC inokwahlulwa ibe: Ibanga lokwakha, iBanga lokutya kunye namayeza ngokwenjongo. Okwangoku, uninzi lweemveliso zasekhaya libakala lokwakha. Kwinqanaba lokwakha, isixa se-potty powder sikhulu kakhulu, malunga ne-90% isetyenziselwa umgubo ongezantsi, kwaye okuseleyo kusetyenziselwa ukuqina kwesamente kunye neglu.
2. Zininzi iintlobo ze-hydroxypropyl methylcelculose (i-HPMC), kwaye yintoni umahluko ekusebenziseni kwabo?
I--Answer: I-HPMC inokwahlulwa ibe luhlobo lwethutyana kunye nohlobo olushushu. Iimveliso zemodi zethutyana zisasaza ngokukhawuleza emanzini abandayo kwaye zinyamalala emanzini. Ngeli xesha, ulwelo alunanto yokufakwa, kuba i-HPMC ichithwa njengamanzi kwaye ayinasiphelo sokwenyani. Emva kwemizuzu emi-2, i-viscosity ye-ulwelo ngokuthe ngcembe yanda, yakha i-viscous ebonakalayo. Iimveliso zokuchitha ubushushu, xa zidibana namanzi abandayo, zinokusasazeka ngokukhawuleza emanzini ashushu, kwaye inyamalale emanzini ashushu. Xa iqondo lobushushu liye kwiqondo lokushisa (imveliso yenkampani yethu ingama-65 degrees Celsius), i-viscofity ivela kancinci de ivele i-collous engabonakaliyo. Uhlobo olushushu olushushu lunokusetyenziswa kuphela kwi-podty powder nodaka. Kwiglue yeglue kunye nepeyinti, ukubethwa kuka-Likedon kuya kwenzeka kwaye akunakusetyenziswa. Uhlobo lwethutyana lunoluhlu olubanzi lwezicelo. Ingasetyenziswa kwi-poceble yomgubo kunye nodaka, kunye neglu yolwelo kunye nepeyinti, ngaphandle kokuphikisana.
3. Zithini iindlela zokuchithwa kwe-hydroxypropyl methylcelcelgalose (HPMC)?
-I-Afrikansi: Indlela yokuchithwa kwamanzi eshushu: Oko i-HPMC ayichithwanga emanzini ashushu, i-HPMC inokuba isasazeke ngendlela efanayo emanzini okuqala, emva koko inyibilikisiwe ngokukhawuleza. Iindlela ezimbini eziqhelekileyo zichazwe ngolu hlobo lulandelayo:
1) Beka inani elifunekayo lamanzi ashushu kwisikhongozeli kwaye ubushushu malunga nama-70 ° C. I-hydroxypropyl methylcelcelsulose yongezwa ngokuthe ngcembe, ekuqaleni i-HPMC ifakwe kumphezulu wamanzi, emva koko yazenzela ngokuthe ngcembe isilayidi.
2), Yongeza i-1/3 okanye i-2/3 yexabiso elifunekayo lamanzi esi sitya, kwaye usitshise ukuya kwi-70 ° C, ngokwendlela ye-1), ukusasaza i-HPMC i-HPMC; Emva koko yongeza inani elisele lamanzi abandayo ukuya kwamanzi ashushu kwi-slirry, umxube wapholwa emva kokuvuselela.
Indlela yokudibanisa i-powder Ikona encinci encinci. Umgubo uya kunyibilikisa ngoko nangoko kunxibelelana namanzi. Indlela ye--tis isetyenziswa yi-putty powder kunye nabavelisi bodaka. [HYDROXYPOPLL methylcelceltulose (i-HPMC) isetyenziswa njenge-tickener kunye nearhente yokugcina amanzi kumda we-podty powder. ]
4. Ungawugweba njani umgangatho we-hydroxypropyl methylcelculose (i-HPMC) ngokulula nangokuthathelayo?
-I-Afrikan-(1) Ubumhlophe: Nangona ubumhlophe abunakufumanisa ukuba i-HPMC kulula ukuyisebenzisa, kwaye ukuba i-HPMC ilula ukuyisebenzisa, kwaye ukuba i-SPIT iyongezwa kwinkqubo yemveliso, iya kuchaphazela umgangatho wayo. Nangona kunjalo, uninzi lweemveliso ezilungileyo lube mhlophe mhlophe. . Uninzi lwe-HPMC eveliswe eHebei yi-80 mesh. Ukuhlekisa kakuhle, ngcono. . Ukuphakama okuphezulu, okungcono, kubonisa ukuba kukho izinto ezingafakwanga kuyo. Ukufakwa kwe-verctoctor olwenziweyo kulungile, kwaye i-proctor ethe tyaba imbi kakhulu, kodwa ayinakuthethwa ukuba umgangatho wesakhiwo esithe nkqo ungcono kuneso sixhobo esithe nkqo, kwaye zininzi izinto ezimisela umgangatho wemveliso. . Ubuninzi obuthile bukhulu, kuba ngokubanzi kuba umxholo we-hydroxypropy kuwo uphakamile, kwaye umxholo we-hydroxypropy uphuphume, ukugcinwa kwamanzi kungcono.
5. Ixabiso le-hydroxypropyl methylcelcelculose (HPMC) e-Itty Powder?
-I-ASPHUPHAT: Ixabiso le-HPMC elisetyenziswa kwizicelo ezisebenzayo ziyahluka ngokuxhomekeka kwimozulu, ubushushu, umgangatho we-ash ye-ash ye-ash kunye "nomgangatho ofunwa ngabathengi". Ngokubanzi, uphakathi kwe-4 kg kunye ne-5 kg. Umzekelo, uninzi lwe-powty powder eBeijing yi-5 kg; Uninzi lwe-poty powty powty eGuizhou yi-5 kg ehlotyeni kunye ne-4.5 kg ebusika;
6. Luthini uVekyusis ofanelekileyo we-hydroxypropyl methylcelcellulose (HPMC)?
-I-Asnwer: I-Putty Powder ikakhulu yi-100,000 yuan, kwaye udaka ifuna ngakumbi, kwaye kulula ukuyisebenzisa kwi-150,000 yuan. Ngaphezu koko, eyona ndima ibaluleke kakhulu ye-HPMC kukugcina amanzi, kulandelwe ngokulandelelana. E-Putty Powder, logama nje ukugcinwa kwamanzi kulungile kwaye i-viscosity iphantsi (70,000-80,000), kunokwenzeka. Ewe kunjalo, i-vickosity iphezulu, kwaye ukugcinwa kwamanzi ngokuhambelana. Xa i-viscosity idlula i-100,000, isiphumo sokujonga ukugcinwa kwamanzi akuninzi.
7. Zeziphi izikhombisi eziphambili ze-hydropylpropyl methylcelculose (HPMC)?
I--Answer: i-hydroxypropy yomxholo kunye ne-viscofity, uninzi lwabasebenzisi abakhathalelayo ezi zikhombisi zimbini. Ngaphezulu komxholo we-hydroxypropy, kungcono ukugcinwa kwamanzi. I-viscosity ephezulu, ukugcinwa kwamanzi, ngokulinganayo (kunokuba ugqibelele) ungcono, kwaye uvimba ophezulu, usebenzise ngcono udaka lwesamente.
8. Zeziphi izixhobo eziphambili ze-hydroxypropyl methylcelcelcelce (i-HPMC)?
-I-A: Ezona zinto ziphambili ze-HydroxyPOpyl MethylcelceLXhosa (HPMC): I-HPMC ecocekileyo, i-propyl oxide, i-propyl oxide, i-propylene oxide, i-acid, i-toonene, i-Iyopropanol, njl.
9. Yeyiphi eyona ndima iphambili ye-HPMC kwi-HPMC yomgubo we-DATTY, kwaye ikhona i-chemistry?
-I-Answer: I-HPMC inemisebenzi emithathu yokutsalwa, ukugcinwa kwamanzi kunye nokwakhiwa komgubo we-sty powder. Ukutyibilika: I-SelelUlose inokuba ihlawulwe ukunqumamisa, gcina iyunifomu yesisombululo kwaye iyaguquka, kwaye iyaxhathisa. Ukugcinwa kwamanzi: Yenza umgubo wokubekwa kancinci, kwaye uncede ukuphendula kwe-ASH Calcium phantsi kwesenzo samanzi. Ulwakhiwo: I-Seleculose inefuthe lokunyathela, elinokwenza umgubo obekiweyo unokuphumelela. I-HPMC ayithathi nxaxheba kuyo nayiphi na indlela yokuphendula yemichiza kwaye idlala kuphela indima encedisayo. Ukongeza amanzi kwi-pople powder kwaye uyibeke eludongeni yindlela yokuphendula yemichiza. Ngenxa yokusekwa kwezinto ezitsha, thatha umgubo obekwe eludongeni eludongeni, gxotha ube ngumgubo, kwaye uphinde uyisebenzise. Ayizukusebenza, kuba izinto ezintsha (ze-calcium carbonate) zenziwe. ) phezulu) phezulu. Amacandelo aphambili e-Ash Calcium Powder yile: umxube we-CA (oh) 2, i-Cao kunye ne-CAOS kunye ne-CAOS kunye ne-2 (OH) 2 + I-COO ** 2O ASH Calcium emanzini nasemoyeni phantsi kwesenzo se-CO2, i-calcium carbonate ivelisiwe, ngelixa i-HPMC igcina amanzi kwaye incedise ekuphenduleni kwe-ASH Calcium, kwaye ayithathi nxaxheba kuyo nayiphi na impendulo.
I-10. I-HPMC ayi-ionic selsulose ether, ke yeyiphi i-non-ionic?
-Impendulo: Kwimigaqo ye-DARDAMS, i-ions zizinto ezingasebenziyo emanzini. I-iorisry ibhekisa kwinkqubo apho i-electrolyte ihluthwe kwii-ions) ezihambayo kwi-Solvent ebizwa ngokuba yi-Solvent ekhethekileyo (njengamanzi, utywala). Umzekelo, i-sodium chloride (Ityuwa), ityuwa idliwe yonke imihla, inyibilikiswe emanzini nasekuhlawuleni ihlawulwe ngokukhululekileyo i-Ions eshukumayo ngokukhululekileyo kwaye ihlawulwe kakuhle. Oko kukuthi, xa i-HPMC ifakwe emanzini, ayihambelani kwi-Ions, kodwa ikho ngohlobo lweeMolekyuli.
