01.I-Hydroxyethyl Cellulose
Njenge-surfactant engeyona i-ionic, i-hydroxyethyl cellulose ayinayo nje imisebenzi yokumisa, ukuqina, ukuhlakaza, ukuntanta, ukubopha, ukwakha ifilimu, ukugcinwa kwamanzi kanye nokunikeza i-colloid evikelayo, kodwa futhi inezakhiwo ezilandelayo:
1. I-HEC iyancibilika emanzini ashisayo noma abandayo, futhi ayivuthi lapho izinga lokushisa eliphezulu noma libila, ukuze ibe nezici eziningi zokuncibilika kanye nokuthamba, kanye ne-gelation engashisi;
2. Uma kuqhathaniswa ne-methyl cellulose eyaziwayo kanye ne-hydroxypropyl methyl cellulose, ikhono lokuhlakaza le-HEC libi kakhulu, kodwa i-colloid evikelayo inekhono eliqine kakhulu.
3. Umthamo wokugcina amanzi uphakeme ngokuphindwe kabili kunowe-methyl cellulose, futhi unokulawulwa okungcono kokugeleza kwamanzi.
Izinyathelo Zokuqapha Uma Usebenzisa:
Njengoba i-hydroxyethyl cellulose ephathwe phezulu iyi-powder noma i-cellulose eqinile, kulula ukuyiphatha nokuyincibilikisa emanzini uma nje kuphawulwe izinto ezilandelayo.
1. Ngaphambi nangemva kokufaka i-hydroxyethyl cellulose, kumele ivuselelwe njalo kuze kube yilapho ikhambi selicacile futhi licacile ngokuphelele.
2. Kumele ihlungwe kancane kancane emgqonyeni wokuxuba. Ungafaki ngqo i-hydroxyethyl cellulose eyenziwe yaba yizigaxa noma amabhola emgqonyeni wokuxuba ngobuningi obukhulu noma ngokuqondile.
3. Izinga lokushisa lamanzi kanye nenani le-pH lamanzi kunobudlelwano obubalulekile nokuncibilika kwe-hydroxyethyl cellulose, ngakho-ke kufanele kunakwe ngokukhethekile.
4. Ungalokothi ufake ezinye izinto ze-alkaline engxubeni ngaphambii-hydroxyethyl celluloseUfulawa ufudunyezwa ngamanzi. Ukuphakamisa inani le-PH ngemva kokufudumala kuyasiza ekuncibilikeni.
Ukusetshenziswa kwe-HEC:
1. Ngokuvamile isetshenziswa njenge-ejenti yokujiya, i-ejenti yokuvikela, i-glue, i-stabilizer kanye ne-additive yokulungiselela i-emulsion, i-gel, i-ointment, i-lotion, i-ejenti yokuhlanza amehlo, i-suppository kanye nethebhulethi, isetshenziswa futhi njenge-hydrophilic gel, izinto zamathambo, ukulungiswa kwamalungiselelo okukhululwa kwamathambo okuqhubekayo, futhi ingasetshenziswa njenge-stabilizer ekudleni.
2. Isetshenziswa njenge-ejenti yokulinganisa embonini yezindwangu, ukubopha, ukuqina, ukuhlanganisa, ukuzinzisa kanye nezinye izinto ezisizayo emikhakheni ye-elekthronikhi kanye nemboni yokukhanya.
3. Isetshenziswa njengesithambisi kanye nesinciphisi se-filtrate soketshezi lokubhoboza olusekelwe emanzini kanye noketshezi lokuqedela, futhi inomphumela osobala wokujiya koketshezi lokubhoboza ngamanzi anosawoti. Ingasetshenziswa futhi njenge-ejenti yokulawula ukulahlekelwa koketshezi lwesimende somthombo wamafutha. Ingaxhunyaniswa nama-ion ensimbi e-polyvalent ukuze kwakheke ama-gel.
5. Lo mkhiqizo usetshenziswa njengesihlanzisi soketshezi lokuqhekeka kwejeli olusekelwe emanzini, i-polystyrene kanye ne-polyvinyl chloride ekukhiqizweni kokuqhekeka kwamafutha. Ungasetshenziswa futhi njengesithambisi se-emulsion embonini yopende, isithambisi esizwela umswakama embonini ye-elekthronikhi, isivimbeli sokujiya kwesamente kanye ne-ejenti yokugcina umswakama embonini yokwakha. Izinamathiseli ze-glazing kanye ne-toothpaste embonini ye-ceramic. Usetshenziswa kabanzi ekunyatheliseni nasekudayeni, ezindwangu, ekwenzeni amaphepha, kwezokwelapha, ekuhlanzeni, ekudleni, osikilidi, ezibulala-zinambuzane kanye nasezintweni zokucima umlilo.
02. I-Hydroxypropyl Methyl Cellulose
1. Imboni yokumboza: Njengesithambisi, isihlakazi kanye nesiqinisi embonini yokumboza, ihambisana kahle namanzi noma izinyibilikisi eziphilayo. njengesisusi sopende.
2. Ukukhiqiza ngobumba: kusetshenziswa kabanzi njengesibopho ekwenziweni kwemikhiqizo ngobumba.
3. Okunye: Lo mkhiqizo usetshenziswa kabanzi nasesikhumbeni, embonini yemikhiqizo yephepha, ekulondolozweni kwezithelo nemifino kanye nasembonini yezindwangu, njll.
4. Ukuphrinta uyinki: njengesithako sokujiya, isihlakazi kanye nesiqinisi embonini uyinki, kuhambisana kahle emanzini noma ezincibilikisini eziphilayo.
5. Ipulasitiki: isetshenziswa njenge-ejenti yokukhulula ukubumba, isithambisi, i-lubricant, njll.
6. I-Polyvinyl chloride: Isetshenziswa njengesihlanzi ekukhiqizweni kwe-polyvinyl chloride, futhi iyi-ejenti eyinhloko yokusiza yokulungiselela i-PVC nge-suspension polymerization.
7. Imboni yokwakha: Njenge-ejenti yokugcina amanzi kanye ne-retarder ye-cement mortar, i-mortar iyakwazi ukupompa. Isetshenziswa njenge-binder ekuplasteni i-paste, i-gypsum, i-putty powder noma ezinye izinto zokwakha ukuthuthukisa ukusabalala nokwandisa isikhathi sokusebenza. Isetshenziswa njenge-paste ye-ceramic tile, imabula, umhlobiso wepulasitiki, njengesithuthukisi se-paste, futhi inganciphisa nenani le-samente. Ukugcinwa kwamanzi kwe-hydroxypropyl methylcelluloseI-HPMCkungavimbela ukuqhekeka kwe-slurry ngenxa yokoma ngokushesha kakhulu ngemva kokufaka, futhi kuthuthukise amandla ngemva kokuqina.
8. Imboni yezemithi: izinto zokumboza; izinto zefilimu; izinto ze-polymer ezilawula izinga lokulungiselela ukukhululwa okuqhubekayo; izinto zokuqinisa; izinto zokumisa; izinto zokubopha amaphilisi; izinto zokubopha.
Imvelo:
1. Ukubukeka: impuphu emhlophe noma engemhlophe nhlobo.
2. Usayizi wezinhlayiya; Izinga lokudlula kwe-mesh engu-100 likhulu kuno-98.5%; Izinga lokudlula kwe-mesh engu-80 lingu-100%. Usayizi wezinhlayiya zemininingwane ekhethekile ungama-mesh angu-40 ~ 60.
3. Izinga lokushisa le-carbonization: 280-300℃
4. Ubuningi obubonakalayo: 0.25-0.70g/cm (ngokuvamile cishe u-0.5g/cm), amandla adonsela phansi athile 1.26-1.31.
5. Izinga lokushisa lokushintsha umbala: 190-200℃
6. Ukucindezeleka kobuso: Isixazululo samanzi esingu-2% singu-42-56dyn/cm.
7. Ukuncibilika: kuncibilika emanzini nakwezinye izincibilikisi, njengesilinganiso esifanele se-ethanol/amanzi, i-propanol/amanzi, njll. Izixazululo zamanzi zisebenza phezulu. Ukucaca okuphezulu nokusebenza okuzinzile. Imininingwane ehlukene yemikhiqizo inezinga lokushisa elihlukile lejeli, futhi ukushintsha kokuncibilika kuyashintsha nge-viscosity. Uma i-viscosity iphansi, kulapho ukuncibilika kuba kukhulu khona. Imininingwane ehlukene ye-HPMC inezakhiwo ezihlukile. Ukuncibilika kwe-HPMC emanzini akuthinteki yinani le-pH.
8. Ngokuncipha kokuqukethwe kweqembu le-methoxy, iphuzu lejeli liyakhula, ukuncibilika kwamanzi kuyancipha, futhi umsebenzi wobuso be-HPMC uyancipha.
9. I-HPMCfuthi inezici zekhono lokujiya, ukumelana nosawoti, impuphu yomlotha ephansi, ukuqina kwe-pH, ukugcinwa kwamanzi, ukuqina kobukhulu, izakhiwo ezinhle kakhulu zokwakha ifilimu, kanye nobubanzi bokumelana kwama-enzyme, ukuhlakazeka kanye nokuhlangana.
