HPMC inovandudza sei Gypsum-based Bavako Zvivakwa?

HydroxyPropyl methylcellose (HPMC) ndeye isiri-ionic cellulose ther yemakemikari yakagadziriswa kubva kune yakasikwa cellulose. Nekuda kwekuchengetwa kwaro kwemvura Gypsum-based zvinyorwa chinhu chakajairika chekuvaka uye chinoshandiswa zvakanyanya mumukati uye kunze kwemadziro ekushongedza, zvinonamatira uye zviyero. Iyo yekutanga yeHPMC yakavandudza zvakanyanya kuita kwezvinhu zveGypsum-based, kuvaita kuti vanyanya kunaka maererano nekuvaka uye kusimba.

1. HPMC inovandudza mashandiro ekushanda kweiyo gypsum-based zvigadzirwa

Kuvandudza Kuchengetwa Kwemvura
Imwe yemabasa makuru eHPMC ndeyekugadzirisa zvakanyanya kuchengetedza mvura yekuchengeta kwemvura yezvinhu zveGypsum-based. Munguva yeiyo hydration process, gypsum inoda yakakwana mvura kuti ipedze kuomesa musoro. Mvura isina kukwana ichatungamira kusakwana, yakaderedzwa simba uye zvimwe zvinetso. HPMC inogona kuderedza huwandu hwemvura nekuumba yunifomu yemhando yekodhi, nokudaro ichivimbisa kuti hydration maitiro e gypsum inogona kuenderera zvakanaka. Izvi hazvingakuvadzi chete simba rechinyorwa asi zvakare rinotambanudzira zvakare hupenyu hwaro hwebasa. Uye zvakare, kuchengetwa kwemvura kweHPMC kunoita kuti slurry inotsvedza panguva yekuvaka, zvichiita kuti zvive nyore kushandisa uye kudzivirira shrinkage marara anokonzerwa nekurasikirwa kwemvura.

Kuvandudza Kubata
HPMC inogona kuvandudza zvakanyanya basa rekushanda kweGypsum-based zvinhu, kuita kuti zvive nyore kushandisa, nhanho uye calender. Kubata kwayo kwakasimba kunoita kuti slurry yekuchengetedza visikoka uye fluidity, ichiita kuti zvisingakwanisike uye kuyerera. Panguva imwecheteyo, HPMC inovandudza iyo Lubricity yezvinhu zveGypsum, zvichiita kuti inyararire panguva yekuvaka uye nyore kushanda. Izvi zvinonyanya kukosha kune yakakura-nzvimbo pendi kana yekushongedza kwakanaka, kuderedza mukana wekugadzirisa uye kugadzirisa kugona kwekuvaka.

Wedzera maawa ekuvhura
Munguva yekuvaka, zvinhu zveGypsum-based: Ndokunge, iyo nguva yavanogona kushanda) kuve nechokwadi chekuti vashandi vanogona kuzadzisa iyo application kana kuwanda basa mukati menguva yakakodzera nguva. HPMC inogona kunonoka kubuda kwemvura kuburikidza nekuchengetwa kwemvura kwayo uye nekukora zvinhu, nekudaro zvichikonzera nguva yekutanga yezvinyorwa. Izvi zvinopa vashandi nguva yakawanda yekugadzirisa zvakanaka uye nechokwadi chekuvaka hunhu.

2. HPMC inovandudza iyo mechantics zvivakwa zve gypsum-based zvigadzirwa

Wana kuwedzera
Iyo yekuchengetwa kwemvura yeHPMC haigone kungove nechokwadi cheiyo hyprecuration yeGypsum, asi zvakare tamba nebasa rakanaka mukusimudzira yekutanga simba rekusimbisa kweGypsum-based. Munguva yehydration process, HPMC inogadzirisa kugoverwa kwemvura kuti iite iyo Gypsum crystal yekisimusi yakawanda uye yunifomu, nekuvandudza simba rekutanga rezvinyorwa. Panguva imwecheteyo, kuwedzera kweHPMC kunoderedzawo hupfumi mune slurry, kubvumira iyo yeGypsum-yakavakirwa zvinyorwa zvekuratidzira simba repamusoro-simba rekusimbisa mushure mekuomesa.

Kuvandudza Crack Kudzivisa
Gypsum-based zvinhu zvinowedzera kuomesa shringege marara panguva yekuomesa, iyo inokonzerwa nevhoriyamu shriner inokonzerwa nekuvapurwa kwemvura. HPMC zvinobudirira inoderedza kuitika kweiyo yakaoma shringege kutsvaira nekugadzirisa mwero wekubereka kwemvura uye kuwedzera kuomarara kwechinyorwa. Uye zvakare, iyo plasticity yeHPMC inopa iyo mwero wekukora uye kushushikana panguva yekuomesa uye kuomesa maitiro, kuenderera mberi nekuwedzera kwekupenga kupokana. Izvi zvinogona kuderedza zvinobudirira dambudziko remukati memukati makapuru zvinokonzerwa nekushomeka kwakaoma apo zvigadzirwa zveGypsum zvinowanikwa munzvimbo dzakakura senge madziro emukati uye emadziro ekunze.

3. Mhedzisiro yeHPMC pane kujaira kwezvinhu zveGypsum-based

Kuvandudza kusununguka-thaw kuramba
Nekuda kwechimiro chayo chakasarudzika, zvinhu zveGypsum zvinokanganiswa zviri nyore neyekupedzisira-thaw matatya mumamiriro ezvinhu, zvichitungamira kumatambudziko akadai seyakaderedzwa simba uye mamiriro ekunze. Mushure mekunge HPMC yakaunzwa muGypsum zvinhu, inogona kuderedza kutama kwemvura muchinyorwa ichi kuburikidza nekuchengetwa kwemvura uye nekudzikisira kwezvakashata, nekudaro kuderedza kukuvadzwa kwezvinhu zvakakonzerwa neyekutsungirira-thaw matatya. Uye zvakare, iyo firimu-inogadzira midziyo yeHPMC inogona kuumba firimu rekudzivirira pamusoro pezvinyorwa, kuenderera mberi nekuwedzera iyo yezvinhu zvisingaravire-thaw kuramba.

Kuvandudza Carbonation Kudzivisa
Gypsum-yakavakirwa zvinhu zvinowanzoitika kune carbonization maitiro kana yakavhurwa nemhepo, zvichikonzera kurasikirwa kwesimba uye pamusoro pechidzitiro. Iyo firimu-inogadzira mhedzisiro yeHPMC inogona kuumba dense yekudzivirira denderedzwa pamusoro pezvinyorwa zvekudzivirira kuwanda kweCarbon dioxide, nekudaro kuderedza kuitika kwecaronization maitiro. Panguva imwecheteyo, iyo mvura yekuchengetwa kwemvura yeHPMC inoita kuti Gypsum zvakanyanya hydrate, kuwedzera kuwedzeredza kuita kwekunyepedzera kwekunyepedzera. Izvi zvinobvumira zvinyorwa zveGypsum-based kuratidza zviri nani kusakwana mukushandiswa kwenguva refu, kunyanya kana uchishandiswa kunze kwekunze.

4. Kuvandudzwa kwenzvimbo yekushambadzira yeHPMC kuenda kuGypsum-based zvigadzirwa

Kuvandudza kudzikisira kwemvura
Gypsum-based zvinhu zvinowanzo nyorova uye nyungudika nyore nyore kana zvichiratidzwa nemvura, iyo inogumira kushandiswa kwavo munzvimbo dzakanyorova. Iyo yekuchengetwa kwemvura uye firimu-inoumba zvivakwa zveHPMC inogona kusimudzira kudzikisira kwemvura kwezvinhu zveGypsum, zvichiita kuti vasarikirwe nekukanda kwemvura munzvimbo dzakanyorova munzvimbo dzakanyorova. Nekugadzira iyo mvura yemvura pamusoro pechiso, HPMC inoita kuti zvinhu zveGypsum kuchengetedza zvinhu zvakanaka zvemuviri uye kusimba mushure mekusangana nekunyorova, zvichiita kuti isanyanyoke kuora.

Kuvandudza kuramba kumakemikari kurongeka
HPMC inogona zvakare kuvandudza kumakemikari kurwisa kwezvinhu zveGypsum-based. Iyo defense firimu denderedzwa iyo mafomu pane iyo zvinhu kwete kungozvivharira kupindira kwemanyoro, asi zvakare inodzivirira kupinza kweiyo acid uye alkali zvinhu uye inoderedza kukuvara kwezvinhu zvinokonzerwa nemakemikari corrosion. Iyi pfuma inobvumira zvigadzirwa-zvakavakirwa-zvigadzirwa kuti zvishandiswe munzvimbo dzakawanda dzekudaidzwa, dzakadai sevaya vari muzvivakwa zveindasitiri zvinoiswa pasi pekurwiswa kwemakemikari.

Kuburikidza nemabasa mazhinji akasiyana akadai sekuchengetwa kwemvura, kuremerwa kwemvura, HPMC yakanyanya kugadzirisa basa rekushanda, manhamba, uye kusimbiswa kwekuvakira kweGypsum zvivakwa. Kuwedzera kweHPMC hakungovandudza kugadzirwa kwekuvharirwa kwezvinhu zveGypsum-based uye zvakare kuchinjika, kuchipa tarisiro yechokwadi mune yekuvakwa munda yekuvaka.
