HEMC yePutty Powder Inopikisa Base Cracking uye Coating Peeling

Putty poda inoshandiswa zvakanyanya mukuvaka kuzadza nekugadzirisa makatsemuka, maburi, uye kumwe kusakwana mumadziro uye sirin'i. Nekudaro, rimwe rematambudziko ekushanda ne putty kuve nechokwadi chekuti inonamira zvakanaka kumusoro uye haina kutsemuka kana kupepeta nekufamba kwenguva. Izvi zvinonyanya kukosha kana uchishandisa putty sehwaro hwekupenda kana mamwe marudzi ekupfeka. Imwe nzira yekuvandudza kushanda kweputty munyaya iyi ndeyekuwedzera Hydroxyethyl Methyl Cellulose (HEMC) kumusanganiswa. Muchikamu chino, tichakurukura mabhenefiti ekushandisa HEMC mune putty poda kuramba kutsemuka kwepasi uye kupeta peeling, pamwe nezvinhu zvekufunga kana uchishandisa HEMC muchikumbiro ichi.

Zvakanakira Kushandisa HEMC muPutty Powder

Kuvandudzwa Kwekunamatira: Chimwe chezvikomborero zvakakosha zvekushandisa HEMC muputty powder inovandudzwa kunamatira. HEMC ipolymer inonyungudika nemvura inogona kubatsira iyo putty kunamatira zvakanyanya kumusoro. Izvi zvinonyanya kukosha kana iyo putty inoshandiswa sehwaro hwekupenda kana mamwe marudzi ekupfeka. Kunatsiridza kunamatira kunogona kubatsira kudzikisira mukana wekutsemuka kwepasi uye kupeta peeling, izvo zvinogona kuvandudza huwandu hwese uye hupenyu hurefu hwechigadzirwa chakapedzwa.

Yakaderedzwa Shrinkage: HEMC inogonawo kubatsira kuderedza shrinkage mu putty. Shrinkage inogona kuitika kana iyo putty yaoma uye ichikwevera kure nepamusoro, zvichitungamira mukutsemuka uye mamwe marudzi ekukuvadza. Nekudzikisa shrinkage, HEMC inogona kubatsira kuve nechokwadi chekuti iyo putty inoramba yakanyatsobatanidzwa nepamusoro, iyo inogona zvakare kubatsira kudzikisa mukana wekutsemuka kwebhesi uye kupeta peeling.

Kuvandudzwa Kwekushanda: HEMC inogonawo kuvandudza kushanda kweputty powder. Inogona kubatsira kuderedza viscosity yezvinhu, zvichiita kuti zvive nyore kusanganisa uye kushandisa. Izvi zvinogonawo kubatsira kuderedza kuwanda kwemvura inodiwa mumusanganiswa, iyo inogona kuvandudza hutano hwese uye kusimba kwechigadzirwa chakapedzwa.

Kuita Kwakanaka Kwekuvaka: Pamusoro pezvikomborero zviri pamusoro, HEMC inogonawo kuvandudza kushanda kwekuvaka kweputty powder. Izvi zvinosanganisira zvinhu zvakaita sesimba rekumanikidza, kusimba kwesimba, uye kuchinjika simba. Nekuvandudza zvivakwa izvi, HEMC inogona kubatsira kuve nechokwadi chekuti putty inokwanisa kumirisana nekushushikana uye madhiri ekushandiswa kwakajairwa, uye kuti inoramba yakarongeka nekufamba kwenguva.

Zvinhu Zvekufunga Kana Uchishandisa HEMC muPutty Powder

Rudzi rweHEMC: Kune akati wandei marudzi eHEMC aripo, imwe neimwe iine akasiyana zvivakwa uye maitiro. Mhando yeHEMC yakanakira putty poda ichaenderana nezvinhu zvakaita sekuda kuenderana, viscosity, uye nzira yekushandisa. Kazhinji, yakaderera kusvika pakati viscosity HEMC inokurudzirwa kune putty powder application.

Kusanganiswa Maitiro: Kuti uone kuti HEMC inoparadzirwa zvakaenzana mukati meputty powder, zvakakosha kutevera nzira yakakodzera yekusanganiswa. Izvi zvinowanzobatanidza kuwedzera HEMC kumvura kutanga uye kuisanganisa zvakakwana usati wawedzera hupfu. Zvakakosha kusanganisa putty powder zvakakwana kuti uone kuti HEMC yakapararira zvakaenzana uye kuti hapana zviputi kana zviputi.

Nhamba yeHEMC: Nhamba yeHEMC inofanira kuwedzerwa kune putty powder ichaenderana nezvinodiwa zvekushandiswa. Muzhinji, huwandu hwe0.2% kusvika ku0.5% HEMC nehuremu hwehupfu hunokurudzirwa kuti hubatanidze zvakakwana, kuderedzwa kuderera, kuvandudzwa kwekushanda, uye kushanda kwakanaka kwekuvaka. Zvisinei, huwandu hweHEMC hunodiwa hunogona kusiyana zvichienderana nemhando chaiyo yeputty powder inoshandiswa
