Methyl Hydroxyethyl Cellulose (MHEC)i-cellulose ether isinganyunguduke mumvura, inoshandiswa zvakanyanya muindasitiri yezvinhu zvekuvaka, kunyanya muma-adhesive emataira. Kuwedzerwa kweMHEC kuma-adhesive emataira hakungogadzirisi kushanda zvakanaka chete asiwo kunowedzera kubatana uye kugara kwenguva refu, zvichiita kuti ive chinhu chakakosha muzvinhu zvemazuva ano zvekuvaka nekushongedza.
1. Kusimba Kwekuita, Kuvandudza Kushanda
Zvinonamira zvemataira zvinoda kushanda zvakanaka, uye kukora kweMHEC chinhu chakakosha pakuita izvi. MHEC inonyunguduka mumvura kuti igadzire chinonamira chakasimba, zvichiwedzera simba rechinhunamira, zvichichidzivirira kuti chisashande panguva yekushandiswa uye zvichivandudza kuramba kutsvedza kwakamira panguva yekuisa. Izvi zvakakosha zvikuru pakuisa madziro, zvichidzivirira mataira kuti asatsvedzerere pasi asati asungwa.
thixotropy yakanaka kwazvo inoita kuti namatire yemataira ifambe zviri nyore kana yakurungwa kana kuiswa, zvichiita kuti ishandiswe zvakanaka. Mushure mekuiswa, inokurumidza kuwana simba rayo rakawanda uye inochengetedza chimiro chayo, zvichivandudza kushanda zvakanaka uye kunyatsorongeka.
2. Kuchengetedza Mvura Kwakavandudzwa uye Kunosimudzira Kunyungudika Kwesimende
Kuchengetedza mvura kwakanyanya kweMHEC chimwe chinhu chakakosha mumachinama emataira. Kuchengetedza mvura kwakanyanya uku kunodzivirira kurasikirwa nemvura nguva isati yakwana kubva mumatope, zvichideredza zvakanyanya kutsemuka kana zvikaiswa pamidziyo inopisa zvakanyanya kana inonyudza mvura zvakanyanya (senge kongiri nezvidhinha).
Kuchengetwa kwemvura yakawanda kunoitawo kuti simende irambe ichinyorova zvakakwana, nokudaro zvichiwedzera simba rekubatanidza uye kugara kwenguva refu kwenamira yemataira. Iyi hunhu hwe "kuchengetedza hunyoro hwemukati" hweMHEC hunoita kuti namira yemataira ishande zvakanaka munzvimbo dzakasiyana-siyana dzakaoma, zvichiita kuti ive yakakodzera kushandiswa kwenamira yakatetepa uye kuiswa kwemataira makuru.
3. Kunamira Kwakawedzerwa uye Kuchinjika
Kunyangwe MHEC pachayo isiri glue, chimiro che colloidal network chainoumba chinobatsira kuwedzera nzvimbo yekubatana uye kufanana kwebond pakati pe tile glue ne substrate, zvichivandudza mashandiro e bonding yese nenzira isina kunanga. MHEC inovandudzawo kuchinjika kwe tile glue, ichiibvumira kuti igone kuchinjika nekupisa kwakanyanya uye kudzikira, kana kufamba kudiki, pasina kutsemuka, nokudaro ichiwedzera hupenyu hwayo hwekushanda.
4. Nguva Yakavandudzwa Yekuvhura uye Hupenyu Hwemuhari
Kuwedzera MHEC kunowedzera nguva yekuvhura kwetiles. Izvi zvinoreva kuti mushure mekushandisa tissue iyi, vashandi vane nguva yakawanda yekuisa mataira. Izvi zvakakosha zvikuru mukuvaka kwakakura, zvichibatsira kuvandudza kushanda zvakanaka kwekuvaka uye kuderedza kugadziriswa patsva.
Uyewo, hupenyu hwehari hwechinamira chetaira hunowedzerwa, zvichireva kuti chinamira chakasanganiswa chinochengetedza kushanda kwacho kwenguva yakati, zvichidzivirira kuomarara nekukurumidza, zvichiita kuti kutarisira kuvaka kuve nyore.
5. Inochengetedza zvakatipoteredza uye yakachengeteka, inogona kushandiswa mumhando dzakasiyana-siyana dzemishonga
MHEC imhando ye cellulose ether isingabatanidzwe mukuita kwe gelling yesimende uye haiburitse magasi anokuvadza, ichizadzisa zvinodiwa nezvinhu zvekuvaka zvakasvibira uye zvine hushamwari kune zvakatipoteredza. Inoenderana zvakanaka nezvimwe zvinowedzera (senge upfu hwe latex hunonyungudika, jecha re quartz, nesimende) uye inogona kushandiswa zvakanyanya mukugadzira mataira ane magiredhi akasiyana-siyana, anosanganisira C1 neC2.
6. Inoenderana neMataira neMasubstrate akasiyana-siyana
MHEC inopa kushanda kwakanaka kwazvo mumaginamisi emataira, kungave akaiswa pamataira madiki echinyakare kana zvigadzirwa zvemazuva ano zvinonyudza mvura yakawanda kana shoma zvakaita sema slabs makuru, mataira ane vitrified, uye mataira epasi. Kushanda kwayo kwakanaka kunobvumirawo kuchinjika kwakakura uye kugadzikana kwakanyanya pamusoro pemhando dzakasiyana-siyana dze substrates, kusanganisira kongiri, madziro ezvidhinha, uye simende yesimbi.
Mashandisirwo makuru eMHEC muma tile adhesiveszvinosanganisira kuwedzera hunhu hwekukora, kuchengetedza mvura, uye kuvandudza kushanda uye kubatana. Chinhu chakakosha chekusimbisa kuti manamatire emataira anoshanda zvakanaka, akasimba, uye ari nyore kushandisa. Nekufambira mberi muhunyanzvi hwekuvaka uye kugadzirwa kwezvinhu zvekuvaka zvakasvibira, kushandiswa kweMHEC mumanamatiri emataira kuchawedzera uye kukosha kwayo kuchakura.
