Mechanically sprayed mortar, inozivikanwawo sejetted mortar, inzira yekupfapfaidza dhaka pamusoro uchishandisa muchina. Iyi nzira inoshandiswa pakuvaka madziro ekuvaka, pasi uye matenga. Maitiro acho anoda kushandiswa kwehydroxypropyl methylcellulose ether (HPMC) sechinhu chakakosha chedhaka rekupfapfaidza. HPMC ine mabhenefiti akati wandei anoita kuti ive yakanakisa yekuwedzera kune mechaniki yekupfapfaidza dhaka.
Kuita kweHPMC muMechanical Spraying Motar
HPMC chinhu chinonyungudika nemvura chinobva kune cellulose. Iyo ine akati wandei akasiyana zvivakwa zvinosanganisira thickening, kuchengetedza mvura uye kusunga. Zvinhu izvi zvinoita kuti HPMC ive yekuwedzera yakakosha kune michina yakapfapfaidza madhaka. Kukobvura uye kuchengetedza mvura kwakakosha mukushandiswa kwemakanika akapfapfaidzwa madhaka. Vanova nechokwadi chokuti dhaka rinogara pamwe chete, rinonamatira kumusoro, uye harina kumhanya.
HPMC inogona zvakare kushandiswa sebhainda remuchina wekupfapfaidza dhaka. Inobatsira kusungira dhaka zvidimbu pamwe chete, kuve nechokwadi chekunamatira kwakasimba kumusoro. Iyi ficha yakakosha nekuti inoita kuti dhaka rekupfapfaidza rive nekugara kwenguva refu uye rinodzivirira kubva kupepeta kubva pamusoro.
Zvakanakira zveHPMC zvemakanika yekupfapfaidza dhaka
1. Kuvandudza kushanda
Kuwedzera HPMC kune mechaniki yekupfapfaidza dhaka kunogona kuvandudza kushanda kwayo. Inowedzera kukwanisa kwedhaka kunamatira kumusoro, kudzivirira kurasikirwa kwayo. Iyi ficha inonyanya kukosha kana uchishanda pamadziro kana sirin'i kuona kuti dhaka haribvi.
2. Wedzera kuchengetwa kwemvura
HPMC ine yakanakisa kuchengetedza mvura, inova yakakosha pfuma yemakanika yekupfapfaidza dhaka. Kunyange panguva yekuvaka, dhaka rinoramba riine mvura, zvichiita kuti chigadzirwa chekupedzisira chive chakasimba uye chinogara kwenguva refu.
3. Kunamatira zviri nani
HPMC inoshanda sebhainda, ichisunga zvimedu zvemichini yakapfapfaidzwa dhaka pamwechete kuti inamire zviri nani. Ichi chivakwa chinovimbisa kuti dhaka rinonamira kumusoro kwekuita kwenguva refu uye rinodzivirira kubva kupepeta kubva pamusoro.
4. Deredza kutsemuka
Kana yawedzerwa kumakanika yekupfapfaidza dhaka, HPMC inoderedza njodzi yekutsemuka. Iyo inoumba chisungo chakasimba mukati medhaka, ichichibvumira kutsungirira kudzvinyirirwa uye mitoro isingazivikanwi. Izvi zvinoguma nechigadzirwa chakasimba chekupedzisira chisingazotsemuka kana kusvuura mushure mekushandisa.
Kushandiswa kweHPMC muMechanical Spraying Motar
Kuti uwane mibairo yakanaka kwazvo nemakanika ekupfapfaidza dhaka, huwandu chaihwo uye mhando yeHPMC inofanirwa kushandiswa. HPMC inofanira kunyatsosanganiswa nezvinhu zvakaoma kuti ive nechokwadi chekugoverwa kwakafanana. Huwandu hweHPMC hunodiwa hunoenderana nezvinhu zvakaita semhando yepasi uye inodiwa maitiro ekuita kwedhaka.
Madhaka akaiswa muchina akachinja indasitiri yekuvaka, uye kuwedzerwa kweHPMC kunounza zvikomborero zvakati wandei zvinosanganisira kuvandudzwa kwekushanda, kuwedzera kuchengetwa kwemvura, kunamira kuri nani uye kuderedzwa kutsemuka. HPMC yave chikamu chakakosha chemichina yekupfapfaidza dhaka, uye maitiro ayo akanaka haagone kushomeka. Kushandisa kwakaringana kweHPMC mumakanika ekupfapfaidza madhaka kunogona kuve nechokwadi chekugara, chinogara kwenguva refu chigadzirwa chinosangana neakaomesesa ekuvaka zviyero.
