1. Iyini inhloso enkulu ye-hydroxypropyl methyl cellulose (HPMC)?
I-HPMC isetshenziswa kabanzi ezintweni zokwakha, ezinengilazi, izinsalela zokwenziwa, izitsha zobumba, imithi, ukudla, izindwangu, ezolimo, izimonyo, ugwayi nezinye izimboni.
I-HPMC ingahlukaniswa ngebanga lokwakha, ibanga lokudla kanye nebanga lezokwelapha ngokwenhloso yalo.
Njengamanje, imikhiqizo eminingi yasekhaya ingeyezinga lokwakha. Ebangeni lokwakha, i-putty powder isetshenziswa ngenani elikhulu, cishe i-90% isetshenziselwa i-putty powder, kanti enye isetshenziselwa udaka lukasimende neglue.
2. Kunezinhlobo ezimbalwa ze-hydroxypropyl methyl cellulose (HPMC). Uyini umehluko phakathi kokusetshenziswa kwazo?
I-HPMC ingahlukaniswa ngohlobo olusheshayo kanye nohlobo oluncibilikayo olushisayo.
Umkhiqizo osheshayo uhlakazeka ngokushesha emanzini abandayo futhi unyamalale emanzini. Ngalesi sikhathi, uketshezi alunayo i-viscosity, ngoba i-HPMC ihlakazekile emanzini futhi ayincibiliki ngempela. Cishe imizuzu emi-2, i-viscosity yoketshezi yanda kancane kancane, yakha i-viscous colloid esobala.
Uhlobo olusheshayo, uhla olubanzi lwezinhlelo zokusebenza, lungasetshenziswa ku-putty powder nodaka, kanye neglue ewuketshezi nopende.
Umkhiqizo oncibilikayo oshisayo, lapho uhlangana namanzi abandayo, ungahlakazeka ngokushesha emanzini ashisayo futhi unyamalale emanzini ashisayo. Lapho izinga lokushisa lehla lifinyelela ezingeni elithile lokushisa, i-viscosity ibonakala kancane kuze kube yilapho kwakheka i-viscous colloid esobala.
Uhlobo lwe-hot melt lungasetshenziswa kuphela ku-putty powder nodaka.
3. Yiziphi izindlela zokuchithwa kwe-hydroxypropyl methyl cellulose (HPMC)?
Indlela yokuchithwa kwamanzi ashisayo: Njengoba i-HPMC ingancibiliki emanzini ashisayo, i-HPMC ingahlakazwa ngokufanayo emanzini ashisayo esigabeni sokuqala, bese incibilika ngokushesha lapho isipholile. Izindlela ezimbili ezijwayelekile zichazwa kanje:
(1) Faka inani elidingekayo lamanzi ashisayo esitsheni bese ushisa kuze kufike ku-70°C. Kancane kancane engeza i-hydroxypropyl methylcellulose ngokunyakazisa kancane, qala i-HPMC intante phezu kwamanzi, bese kancane kancane wenze udaka, bese upholisa udaka ngokunyakazisa.
(2). Faka i-1/3 noma 2/3 yenani elidingekayo lamanzi esitsheni bese usishisa ku-70°C. Ngokwendlela engenhla, hlakaza i-HPMC ukuze ulungiselele udaka lwamanzi ashisayo; bese wengeza inani elisele lamanzi abandayo ku-slurry wamanzi ashisayo. Ku-slurry, pholisa ingxube ngemva kokugqugquzela.
Indlela yokuxuba uphuphu: Xuba i-HPMC powder nenani elikhulu lezinye izithako eziyimpuphu nge-mixer, bese ufaka amanzi ukuze uncibilike, bese i-HPMC ingancibilika ngalesi sikhathi ngaphandle kokugoqa, ngoba ikhona ngalinye elincane, kukhona ingcosana kuphela ye-HPMC. Impushana izoncibilika ngokushesha lapho ihlangana namanzi.
4. Indlela yokwahlulela ikhwalithi ye-hydroxypropyl methylcellulose (HPMC) kalula nangendlela enembile?
(1) Ubumhlophe: Nakuba ubumhlophe bungakwazi ukunquma ukuthi i-HPMC kulula yini ukuyisebenzisa, futhi uma isicwebezeli sengezwa kunqubo yokukhiqiza, sizothinta ikhwalithi yayo. Nokho, iningi lemikhiqizo emihle inobumhlophe obuhle.
(2) Ukulunga: Ukucoleka kwe-HPMC kuvamise ukuba yi-80 mesh kanye ne-100 mesh, 120 mesh mincane, ukucoleka kwe-fineness, ngokuvamile kungcono.
(3) Ukudlulisela: Ngemva kokufaka i-HPMC emanzini ukuze yakhe i-colloid esobala, bheka ukudluliselwa kwayo. Ukudlulisa okukhulu, kuba ngcono, okubonisa ukuthi kukhona okuncane okungancibiliki ngaphakathi.
(4) Isilinganiso: uma sikhulu isilinganiso, esindayo siba ngcono. Ukucaciswa okuphezulu ngokuvamile kungenxa yokuqukethwe okuphezulu kwe-hydroxypropyl kuyo, futhi ukuphakama kokuqukethwe kwe-hydroxypropyl, ukugcinwa kwamanzi kungcono.
5. Yiziphi izinkomba zobuchwepheshe eziyinhloko ze-hydroxypropyl methyl cellulose (HPMC)?
Okuqukethwe kwe-Hydroxypropyl kanye ne-viscosity, iningi lazo elikhathazekile ngalezi zinkomba ezimbili. Ukugcinwa kwamanzi ngokuvamile kungcono kulabo abanokuqukethwe okuphezulu kwe-hydroxypropyl. I-viscosity ephezulu, ukugcinwa kwamanzi, isihlobo (kunokuba kuphelele) kungcono, futhi i-viscosity ephezulu, isetshenziswe kangcono odakeni lukasimende.
6. Yiziphi izinto zokusetshenziswa eziphambili ze-hydroxypropyl methyl cellulose (HPMC)?
Izinto zokusetshenziswa eziyinhloko ze-HPMC: ukotini ocolisisiwe, i-methyl chloride, i-propylene oxide, njll.
7. Uyini umsebenzi oyinhloko wokusetshenziswa kwe-hydroxypropyl methyl cellulose (HPMC) ku-putty powder? Ingabe kukhona ukusabela kwamakhemikhali?
Ku-putty powder, i-HPMC idlala izindima ezintathu zokuqina, ukugcinwa kwamanzi kanye nokwakha.
Ukuqina: I-Cellulose ingajiywa ukuze imise futhi igcine umfaniswano wesixazululo naphezulu naphansi, kanye nokunqanda ukuhlehla.
Ukugcinwa kwamanzi: yenza i-putty powder yome kancane, futhi usize i-calcium empunga ukuba isabele ngaphansi kwesenzo samanzi.
Ukwakhiwa: I-Cellulose inomphumela wokugcoba, ongenza i-putty powder ibe nokusebenza okuhle.
I-HPMC ayibambi iqhaza kunoma yikuphi ukusabela kwamakhemikhali, idlala indima yokusekela kuphela.
8. Liyini iphunga le-hydroxypropyl methyl cellulose (HPMC)?
I-HPMC ekhiqizwa indlela yokuncibilikisa isebenzisa i-toluene ne-isopropanol njengesinyibilikisi. Uma ingagezwanga kahle, izoba nephunga eliyinsalela.
9. Ungakhetha kanjani i-hydroxypropyl methylcellulose (HPMC) efanele ngezinhloso ezahlukene?
Ukusetshenziswa kwe-putty powder: imfuneko iphansi, i-viscosity yi-100,000, yanele, into ebalulekile ukugcina amanzi angcono.
Ukusetshenziswa kodaka: izidingo eziphezulu, i-viscosity ephezulu, i-150,000 ingcono.
Ukusetshenziswa kweglue: imikhiqizo esheshayo iyadingeka, ene-viscosity ephezulu.
10. Ukusetshenziswa kwe-hydroxypropyl methyl cellulose (HPMC) ku-putty powder, yini ebangela ukuthi i-putty powder ikhiqize ama-bubbles?
Ku-putty powder, i-HPMC idlala izindima ezintathu zokuqina, ukugcinwa kwamanzi kanye nokwakha. Ungabambi iqhaza kunoma yikuphi ukusabela.
Izizathu zamabhamuza:
1）. Beka amanzi amaningi kakhulu.
2）. Uma ungqimba olungezansi lungasomile, vele usule esinye isendlalelo phezulu, kuzoba lula futhi ukwenza igwebu.
Imikhiqizo yethu ibonakala kakhulu futhi ithembekile ngabathengi futhi izokwanelisa njalo ukuthuthukisa izifiso zezomnotho nezenhlalo zeminyaka eyi-8 I-Exporter China Construction Grade Cellulose HPMC Isetshenziselwa i-Drymix Mortar HPMC, Izinto zethu zihlinzekwa njalo kumaQembu amaningi nezimboni eziningi. Ngaleso sikhathi, imikhiqizo yethu ithengiswa e-USA, Italy, Singapore, Malaysia, Russia, Poland, kanye naseMpumalanga Ephakathi.
I-8 Years Exporter China HPMC, Building Material, Sihlanganisa ukuklama, ukukhiqiza kanye nokuthekelisa kanye nabasebenzi abanekhono abangaphezu kwe-100, uhlelo oluqinile lokulawula ikhwalithi kanye nobuchwepheshe obunolwazi. I-USA, UK, Canada, Europe kanye ne-Afrika njll.
