01.Hydroxyethyl Cellulose
Monga mankhwala osakhala a ionic surfactant, hydroxyethyl cellulose sikuti imangokhala ndi ntchito zoyimitsa, kukhuthala, kufalitsa, kuyandama, kugwirizana, kupanga filimu, kusunga madzi ndi kupereka colloid yoteteza, komanso ili ndi zinthu zotsatirazi:
1. HEC imasungunuka m'madzi otentha kapena ozizira, ndipo siigwa kwambiri kutentha kwambiri kapena kuwira, kotero kuti imakhala ndi mitundu yosiyanasiyana ya kusungunuka ndi kukhuthala, komanso gelation yosatentha;
2. Poyerekeza ndi methyl cellulose yodziwika bwino ndi hydroxypropyl methyl cellulose, mphamvu yobalalitsira ya HEC ndiyo yoyipa kwambiri, koma colloid yoteteza ili ndi mphamvu yamphamvu kwambiri.
3. Mphamvu yosungira madzi ndi yowirikiza kawiri kuposa ya methyl cellulose, ndipo ili ndi kayendedwe kabwino ka madzi.
Malangizo Otsatira Mukagwiritsa Ntchito:
Popeza hydroxyethyl cellulose yokonzedwa pamwamba ndi ufa kapena cellulose yolimba, ndi yosavuta kuigwira ndikusungunuka m'madzi bola ngati zinthu zotsatirazi zatchulidwa.
1. Musanawonjezere hydroxyethyl cellulose komanso mutatha kuisakaniza, iyenera kusunthidwa nthawi zonse mpaka yankholo litawonekera bwino komanso loyera.
2. Iyenera kusefedwa pang'onopang'ono mu mbiya yosakaniza. Musawonjezere mwachindunji hydroxyethyl cellulose yomwe yapangidwa kukhala zipolopolo kapena mipira mu mbiya yosakaniza mochuluka kapena mwachindunji.
3. Kutentha kwa madzi ndi pH ya madzi zili ndi ubale wofunikira ndi kusungunuka kwa hydroxyethyl cellulose, kotero chisamaliro chapadera chiyenera kuperekedwa kwa izo.
4. Musawonjezere zinthu zina zamchere mu chisakanizocho musanagwiritse ntchitohydroxyethyl celluloseUfa umatenthedwa ndi madzi. Kukweza PH pambuyo potenthedwa kumathandiza kuti usungunuke.
Kugwiritsa ntchito HEC:
1. Kawirikawiri imagwiritsidwa ntchito ngati chowonjezera kukhuthala, choteteza, chomatira, chokhazikika komanso chowonjezera pokonzekera emulsion, gel, mafuta odzola, lotion, choyeretsera maso, suppository ndi piritsi, imagwiritsidwanso ntchito ngati gel yophikira madzi, zinthu za mafupa, kukonzekera zokonzekera mafupa zotulutsa nthawi yayitali, ndipo ingagwiritsidwenso ntchito ngati chokhazikika mu chakudya.
2. Imagwiritsidwa ntchito ngati chothandizira kukula m'makampani opanga nsalu, kulumikiza, kukhuthala, kusakaniza, kukhazikika ndi zina zothandizira m'magawo amagetsi ndi makampani opanga magetsi.
3. Imagwiritsidwa ntchito ngati chokhuthala komanso chochepetsera kusefa cha madzi obowola pogwiritsa ntchito madzi ndi madzi omalizidwa, ndipo imakhala ndi mphamvu yowonjezereka mu madzi obowola pogwiritsa ntchito madzi amchere. Ingagwiritsidwenso ntchito ngati chowongolera kutayika kwa madzi mu simenti ya chitsime cha mafuta. Ikhoza kulumikizidwa ndi ma ayoni achitsulo a polyvalent kuti apange ma gels.
5. Chogulitsachi chimagwiritsidwa ntchito ngati chosungunula madzi a gel fracturing fluids, polystyrene ndi polyvinyl chloride popanga mafuta fracturing. Chingagwiritsidwenso ntchito ngati emulsion thickener mu makampani opanga utoto, choletsa chinyezi mumakampani opanga zamagetsi, choletsa simenti coagulation ndi chothandizira kusunga chinyezi mumakampani opanga zomangamanga. Zomatira zopaka utoto ndi mano a makampani opanga zinthu zadothi. Chimagwiritsidwanso ntchito kwambiri posindikiza ndi kupaka utoto, nsalu, kupanga mapepala, mankhwala, ukhondo, chakudya, ndudu, mankhwala ophera tizilombo ndi zozimitsira moto.
02. Hydroxypropyl Methyl Cellulose
1. Makampani Opaka Utoto: Monga chokhuthala, chosungunula, komanso chokhazikika mumakampani Opaka Utoto, chimagwirizana bwino ndi madzi kapena zinthu zachilengedwe.
2. Kupanga zinthu zadothi: zimagwiritsidwa ntchito kwambiri ngati chomangira popanga zinthu zadothi.
3. Zina: Chogulitsachi chimagwiritsidwanso ntchito kwambiri m'makampani opanga zikopa, mapepala, kusunga zipatso ndi ndiwo zamasamba komanso mafakitale opanga nsalu, ndi zina zotero.
4. Kusindikiza inki: monga chokhuthala, chosungunula ndi chokhazikika mumakampani opanga inki, chimagwirizana bwino ndi madzi kapena zinthu zachilengedwe zosungunulira.
5. Pulasitiki: imagwiritsidwa ntchito ngati chotulutsira utomoni, chofewetsa, mafuta odzola, ndi zina zotero.
6. Polyvinyl chloride: Imagwiritsidwa ntchito ngati chosungunula popanga polyvinyl chloride, ndipo ndiye chinthu chachikulu chothandizira pokonzekera PVC ndi suspension polymerization.
7. Makampani Omanga: Monga chosungira madzi komanso choletsa matope a simenti, matopewa amatha kupopedwa mosavuta. Amagwiritsidwa ntchito ngati chomangira matope a pulasitala, gypsum, ufa wa putty kapena zipangizo zina zomangira kuti azitha kufalikira bwino ndikuwonjezera nthawi yogwira ntchito. Amagwiritsidwa ntchito ngati phala la matailosi a ceramic, marble, zokongoletsera zapulasitiki, komanso chowonjezera matope, ndipo amathanso kuchepetsa kuchuluka kwa simenti. Kusunga madzi kwa hydroxypropyl methylcelluloseHPMCZimathandiza kuti matope asasweke chifukwa cha kuuma mofulumira kwambiri mutagwiritsa ntchito, ndikuwonjezera mphamvu mukamaliza kuuma.
8. Makampani opanga mankhwala: zipangizo zokutira; zipangizo za filimu; zipangizo za polima zowongolera liwiro la mankhwala kuti zigwiritsidwe ntchito nthawi zonse; zokhazikika; zinthu zomangira; zomangira mapiritsi; zomangira.
Chilengedwe:
1. Maonekedwe: ufa woyera kapena wosakhala woyera.
2. Kukula kwa tinthu tating'onoting'ono; Chiŵerengero cha maukonde 100 ndi chachikulu kuposa 98.5%; chiŵerengero cha maukonde 80 ndi 100%. Kukula kwa tinthu tating'onoting'ono tomwe tili ndi mfundo zapadera ndi 40 ~ 60 maukonde.
3. Kutentha kwa kaboni: 280-300℃
4. Kuchuluka kooneka: 0.25-0.70g/cm (nthawi zambiri pafupifupi 0.5g/cm), mphamvu yokoka yeniyeni 1.26-1.31.
5. Kutentha kwa mtundu: 190-200℃
6. Kukanika kwa pamwamba: 2% yankho lamadzi ndi 42-56dyn/cm.
7. Kusungunuka: kumasungunuka m'madzi ndi zinthu zina zosungunulira, monga kuchuluka koyenera kwa ethanol/madzi, propanol/madzi, ndi zina zotero. Mayankho amadzimadzi amagwira ntchito pamwamba. Kuwonekera bwino komanso magwiridwe antchito okhazikika. Mafotokozedwe osiyanasiyana azinthu ali ndi kutentha kosiyana kwa gel, ndipo kusungunuka kumasintha ndi kukhuthala. Kukhuthala kukakhala kochepa, kusungunuka kumakhala kwakukulu. Mafotokozedwe osiyanasiyana a HPMC ali ndi makhalidwe osiyanasiyana. Kusungunuka kwa HPMC m'madzi sikukhudzidwa ndi pH.
8. Pamene kuchuluka kwa methoxy group kutsika, mfundo ya gel imawonjezeka, kusungunuka kwa madzi kumachepa, ndipo ntchito ya pamwamba pa HPMC imachepa.
9. HPMCIlinso ndi makhalidwe monga kukhuthala, kukana mchere, ufa wochepa wa phulusa, kukhazikika kwa pH, kusunga madzi, kukhazikika kwa mawonekedwe, mphamvu zabwino kwambiri zopangira filimu, komanso kukana ma enzyme osiyanasiyana, kufalikira ndi kugwirizana.
