Hydroxypropyl methylcellulose ether (MHEC), cellulose ether inowanzoshandiswa mumasisitimu emota akasanganiswa nedry-mix, inoita basa rakakosha mukunamatira neputty powders, zvichiita kuti zviome, kuchengetedza mvura, uye kushanda zvakanaka. Ichi chinhu chakakosha chinokanganisa kugadzikana kwekushanda kwezvinhu uye ruzivo rwekuvaka. Sezvo zvinhu zvekushongedza zvekuvaka zvichikura kusvika pamhando yepamusoro, yakareruka, uye isingakuvadzi nharaunda, mabhenefiti eMHEC ari kuramba achionekwa, zvichiita kuti isatsiviwe mune ese masisitimu ekunamatira neputty powder.
1. Mabhenefiti eMHEC mukushandisa Mataira Anonamira
1.1. Kuchengetedza Mvura Kwakavandudzwa Zvikuru, Kudzivirira Kupera Mvura Munguva Yekutanga
Zvinonamira zvemataira zvinofanirwa kuchengetedza hunyoro hwakakwana mushure mekushandisa kuti simende iwane mvura yakakwana. MHEC ine kugona kwakanaka kwekuchengetedza mvura, inovhara hunyoro zvakasimba uye inodzivirira kupinza mvura nekukurumidza kubva pasi pevhu nenzvimbo, nokudaro:
Kuvandudza simba rekubatanidza kwechinamira chetaira;
Kuderedza njodzi yekuva nenzvimbo dzisina chinhu uye kupatsanurwa;
Kuvandudza mashandiro ekuisira mvura, kuchienderana nezvinodiwa zvekuvaka mataira makuru.
Kuchengetwa kwemvura kwakanyanya kweMHEC kwakakodzera zvikuru kune substrates dzinonyudza mvura zvakanyanya, mamiriro ekunze akaoma, uye kuvaka kwezhizha.
1.2. Kushandiswa Kwakavandudzwa uye Kushanda Kwekukwesha
MHEC ine kugona kwakanaka kwekudzora rheological, ichipa mataira manamira hunhu hunotevera:
Kushanda kwakapfava;
Kudzora ukobvu hwakafanana;
Hunhu husina tambo uye husina kunamira.
Kune vashandi, zviri nyore kugadzira ma "serrations" akafanana, zvichivandudza kushanda zvakanaka kwebasa.
1.3. Hunhu Hwakanaka Hwekudzivirira Kutsvedza
MHEC inonyatso gadzirisa thixotropy yechinamira chemataira, ichiwedzera kuyerera kwayo pasi pesimba rekuchekwa uye inodzorera kugadzikana kwayo nekukurumidza mushure mekushandiswa. Hunhu uhwu hunosimudzira zvakananga kubatwa kwekutanga kwemataira, nekudaro:
Kudzivirira kudonha kwemataira;
Kuvandudza kugadzikana kwekuisa makumbo akamira;
Kuderedza kugadziriswa patsva.
Kuwanda kwemataira akakura uye anorema kunoita kuti MHEC isatsvedzerere zvakanyanya.
1.4. Nguva Yakarebeswa Yekuvhura uye Kushivirira Kwakawedzerwa
MHEC, kuburikidza nekuchengetedza mvura uye kudzora rheological, inoderedza mwero wekurasikirwa kwemvura kubva pamusoro pemataira, zvichibvumira vanoisa nguva yakawanda yekushanda kwemataira, kunyanya yakakodzera kushandiswa munzvimbo huru, kuvandudza kushanda zvakanaka kwekuvaka uye kunaka kwechigadzirwa chakapedzwa.
2. Mabhenefiti eMHEC muPutty Powder
2.1. Kuchengetedzwa Kwemvura Kwakavandudzwa, Kuve Nechokwadi Chekuumbwa Kwemafirimu Akafanana ePutty
Matanda matete eputty anogona kusangana nematambudziko akadai sekuoma, kutsemuka, uye kupwanyika kana mvura isina kuchengetwa zvakanaka. MHEC inogona kuchengetedza mvura yakawanda inogona:
Dzivisa kurasikirwa nemvura nguva isati yakwana kubva muputty;
Iva nechokwadi chekuti kuomesa uye kupora kwakafanana;
Dzivisa kusviba, kuita upfu, uye kutsemuka.
Kukosha kweMHEC kunonyanya kuonekwa pakushandisa putty yekunze kwemadziro kana munzvimbo dzinopisa zvakanyanya.
2.2. Kushanda Kwakawedzerwa uye Kurongeka kweKushandiswa
MHEC inovandudza zvakanyanya mafuta eputty, zvichiita kuti kushandiswa kuve nyore:
Kushandiswa kwakapfava uye kusinganetsi zvakanyanya;
Nzvimbo yakapfava uye yakapfava;
Hazviwanzoitiki kukwenywa kana kuunganidzwa kwemarara.
Izvi zvinobatsira zvakananga pakuvandudza kutsetseka kwemadziro uye kunamira zviri nani kwependi dzinotevera.
2.3. Hunhu Hwakavandudzwa hweMaronda ePutty
Kuburikidza nekukora uye kugadzirisa thixotropic kune system, MHEC inopa putty powder hunhu hunotevera:
Kugadzikana kwakanyanya pakuzorora, kudzivirira kudonha;
Kuyerera kwakawedzerwa pasi pekuchekwa, zvichiita kuti zvive nyore kuisa;
Kuchinjika kwakasimba kune kumhanya kwakasiyana kwekushandisa uye matekiniki.
Saka, vese vatsva nevashandi vane ruzivo vanogona kuwana ruzivo rwuri nani rwekushandisa.
2.4. Kunamira Kwakawedzerwa uye Kusimba Kweputty
Kugona kweMHEC kuchengetedza mvura nekuiparadzira kunoita kuti simende iwane mvura yakakwana, zvinotsiva simende, nezvimwe zvinhu, zvichivandudza simba rekubatana pakati peputty nesubstrate, zvichideredza matambudziko emhando yepamusoro akadai sekutsemuka nekupatsanurwa, uye panguva imwe chete zvichiita kuti putty film iwedzere kusimba uye igare kwenguva refu.
3. Mabhenefiti Akajairika eMHEC muMasisitimu Ese Ari Maviri
Ingave iri muma tile adhesives kana putty powders, mabhenefiti akazara eMHEC anoratidzwa muzvinhu zvinotevera:
Inosanganisa kukora uye mhedzisiro yethixotropic, ichivandudza kugadzikana kwehurongwa
Zvinovandudza kushanda zvakanaka uye zvinowedzera kushanda zvakanaka
Inowedzera kunamira pakati pezvinhu ne substrate
Inobatsira zvikuru kuchengetedza mvura, ichivimbisa kukura kwesimba
Inovandudza kunaka kwekupedzisira kwenzvimbo uye kugara kwenguva refu
Se ether ine cellulose inoshanda zvakanyanya,MHECine basa rakakosha mune zvinonamira zvemataira uye upfu hweputty. Kuburikidza nekuchengetedza kwayo mvura zvakanaka, kudzora rheological, kukora, uye kuvandudza kushanda, MHEC inogona kuvandudza kushanda, kunamira, uye mhando yechigadzirwa chakapedzwa, zvichiita kuti ive imwe yezvinowedzerwa zvakakosha pakuvandudza mashandiro uye kugadzikana mumasisitimu emazuva ano emota yakasanganiswa yakaoma. Kune vagadziri, kusarudza zvine musoro mhando dzeMHEC dzine viscosity yakakodzera, mwero wekutsiva, uye tembiricha yegel kunogona kuwedzera zvakanyanya kukwikwidza kwechigadzirwa uye mukurumbira wemusika.
