Zviwedzerwa zvave zvakajairika chikamu chekunamatira mataira uye chinoita basa rakakosha mukuita kwavo nekubudirira. Kushandiswa kwezvinowedzera mumatairi anonamira kwakakosha muindasitiri yekuvaka yanhasi. Zvinowedzerwa zvinobatsira kusimudzira zvinonamira zvimiro zvakaita sekuchengetedza mvura, kugadzirisika uye kusimba kwechisungo, zvichiita kuti ive yakasimba uye inoshanda. HPMC (Hydroxypropyl Methyl Cellulose) muenzaniso wechimwe chinhu chinowanzo shandiswa muindasitiri yekunamira mataira. Ichi chinyorwa chinotsanangura mabhenefiti ekushandisa HPMC mukugadzira mataira anonamira.
Chii chinonzi HPMCs?
Hydroxypropyl methylcellulose inobva paselulosi uye inoumba hupfu huchena kana huyero. Haina chepfu, haina kunhuwa uye ine yakanakisa solubility yemvura. HPMC inowanikwa ne hydrolysis yemiti yemiti kugadzira cellulose, iyo inozogadziriswa kemikari nekuwedzera methoxy uye hydroxypropyl mapoka kune ether linkages. Inonyungudika mumvura, ethanol uye acetone uye ine zvimwe zvinhu zve organic uye inorganic compounds. Inoshandiswa zvakanyanya mumaindasitiri akadai sekuvaka, cosmetics, chikafu, mishonga uye machira.
Zvakanakira Kushandisa HPMC muTile Adhesives
1. Kuvandudza kuchengetedza kwemvura
Imwe yemabhenefiti makuru ekushandisa HPMC mumatairi anonamira ndeyekuti inovandudza kuchengetedza kwemvura. Kuchengetedzwa kwemvura kwakakosha mukunamira kwekugadzira maitiro sezvo ichivimbisa kuti iyo inonamatira inoramba ichishanda uye haina kuoma nekukurumidza. Kana HPMC yawedzerwa kune inonamira, inosanganiswa nemamorekuru emvura kugadzira gel-kufanana kuenderana. Iyo gel chimiro cheHPMC inova nechokwadi chekuti musanganiswa wekunamatira unoramba wakanyorova uye wakabatana, unovandudza anamira processability uye inosimudzira tile bonding.
2. Kuvandudza kushanda
Kushandiswa kweHPMC mumatairi anonamira kunonatsiridza kushanda, ndiko kuti nyore sei kunamatira kunosanganiswa, kuiswa uye kugadziriswa. Machinability inokosha mukugadzira maitiro sezvo inotarisa kushanda kwemaitiro ekuisa. Kana HPMC yawedzerwa kune zvinonamira, inoita seyakakora, zvichikonzera kuenderana kuri nani uye nyore kubata. Iyo yakagadziridzwa kuenderana kwekunamatira inovimbisa kuti inoramba yakabatana uye inogona kuve nyore kuumbwa, kuumbwa kana kupararira kune yakaenzana nzvimbo kuti igadzire nzvimbo yakatsetseka.
3. Wedzera kusimba kwechisungo
Bond simba rinotarirwa nechisungo pakati pe substrate (tile) uye inonamatira. Kushandisa HPMC mumatairi anonamira kunowedzera simba rebhondi nekuwedzera chisungo pakati petairi neanonamira. Basa reHPMC nderekuwedzera nzvimbo yekubatana pakati pe substrate uye inonamira. Kukurukurirana uku kunoguma nechisungo chakasimba chinogona kumirisana nedzvinyiriro huru uye uremu. Iko kunamatira kwakasimba kwakapihwa neHPMC kunovimbisa kuti mataira anogara munzvimbo kunyangwe munzvimbo dzakakwirira dzemotokari uye anoramba achipikisa masimba emagetsi.
4. Deredza kupera
Sezvo iyo inonamatira inooma, inoderera, ichigadzira mapeji uye nzvimbo pakati pematairi. Magapu nenzvimbo zvinogona kuita sezvisingataridzike uye zvakare kubvumira hunyoro kupinda mukati, izvo zvinogona kuita kuti mataira apedzike. Kushandisa HPMC mumatairi anonamira kunovimbisa kuti chinonamira chinooma zvishoma nezvishoma uye zvakaenzana, chichideredza kuderera. Iyo inononoka kuomeswa inobvumira iyo inonamira kugadzirisa, kuve nechokwadi chekuti tile imwe neimwe inoisa zvakaenzana, ichideredza njodzi yemapupu nekuda kwekuderera.
5. Kuvandudza kusamira kwemamiriro ekunze
Kushandiswa kweHPMC mumatairi anonamira kunogona kuvandudza mamiriro ekunze ekunamatira. HPMC inopa imwe dura redziviriro, kuve nechokwadi chekuti chinonamira chinoramba chakasimba kunyangwe mumamiriro ekunze akaoma. Mamiriro ekunze akadai sekuchinja kwekushisa, humidity nemvura zvinogona kuderedza chisungo chekunamatira uye kuderedza kushanda kwayo. HPMC inopa chivharo chekudzivirira chinodzivirira chinonamira kubva kune yakaoma mamiriro ekunze, kuve nechokwadi kuti chinoramba chichishanda kwenguva yakareba.
mukupedzisa
Kuwedzera HPMC kumatairi anonamira kunopa zvakakosha zvakanakira, kuwedzera kunaka kweanonamatira, kushanda, kusimba uye kusimba. Mabhenefiti anosanganisira kunatsiridza kuchengetwa kwemvura, kuwedzeredzwa kwekugadzirisa, kuwedzera kwesimba rezvisungo, kuderedzwa kuderera uye kunatsiridza mamiriro ekunze. Aya mabhenefiti anogona kukwidziridza kunaka kwemabasa ekuvaka anoramba akasimba uye anoshanda kunyangwe mumamiriro ekunze asina kunaka. Nekuda kwemabhenefiti ayo mazhinji, kushandiswa kweHPMC mumatairi ekunamira kwave chinhu chakajairika cheiyo indasitiri yekunamira yekugadzira mataira. Hurukuro hwayo hwakaita kuti ive yakakurumbira uye sarudzo yekutanga yevashandi vekuvaka pasi rese
