Cement additives hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) is cellulose ether iyo inowanzoshandiswa sekuwedzera simende muindasitiri yekuvaka. Iyo polymer inonyungudika nemvura inotorwa kubva kune yakasikwa cellulose uye yakagadziridzwa kuburikidza nekemikari maitiro kuti ivandudze maitiro ayo ekuita.

HEC inowanzoshandiswa mune sement-based materials kuvandudza kushanda kwavo, simba, uye kusimba. Muchikamu chino, tichakurukura mabhenefiti akasiyana-siyana ekushandisa HEC sechinhu chinowedzera simende uye kuti inogona sei kusimudzira zvinhu zvesimende-based materials.

Kuvandudza Kushanda Kwekushanda Chimwe chezvibatsiro zvekutanga zvekushandisa HEC sekuwedzera simende ndeyokuti inogona kuvandudza kushanda kwesimende-based materials. HEC inogona kuita seyakakora uye rheology modifier, iyo inogona kubatsira kuderedza viscosity yemusanganiswa wesamende uye kuvandudza kuyerera kwayo.

Apo HEC inowedzerwa kune sement-based materials, inogona kuvandudza kupararira kwemusanganiswa uye kuita kuti zvive nyore kushandisa. Izvi zvinogona kubatsira kuderedza kuwanda kwemvura inodiwa kuti uwane kuwirirana kunodiwa, izvo zvinogona kuvandudza simba rose uye kusimba kwe simenti.

Kuchengetedzwa Kwemvura Imwe bhenefiti yekushandisa HEC senge simende yekuwedzera ndeyekuti inogona kuvandudza magadzirirwo emvura emidziyo yesamende-based. HEC inogona kuita semufirimu-kare, iyo inogona kubatsira kugadzira chipingamupinyi chinodzivirira mvura kubva pakubuda nekukurumidza kubva mumusanganiswa.

Izvi zvinogona kubatsira kuvandudza nzira yekurapa simende uye kuona kuti inosvika pakugona kwayo kusimba. Mukuwedzera, kuchengetedzwa kwemvura kwakagadziridzwa kunogonawo kubatsira kuderedza dambudziko rekuputika uye shrinkage mune simenti-based materials, izvo zvinogona kuvandudza kusimba kwavo kwese uye hupenyu hurefu.

Yakavandudzwa Adhesion HEC inogona zvakare kuvandudza adhesion zvivakwa zvesimende-based zvinhu. Apo HEC yakawedzerwa kumusanganiswa, inogona kubatsira kugadzira chimiro chakabatana uye chakasimba chinogona kusungirirwa zvakanyanya nepamusoro iyo inoshandiswa.

Izvi zvinogona kuvandudza simba rose uye kusimba kweiyo simenti-yakavakirwa zvinhu uye kuderedza njodzi yeku delamination kana dhizaini nekufamba kwenguva. Kunatsiridza kunamatira kunogonawo kubatsira kudzikisira huwandu hwekugadzirisa uye kugadzirisa kunodiwa kune simende-yakavakirwa zvinhu, iyo inogona kuve yakakosha-yekuchengetedza mari inobatsira kuindasitiri yekuvaka.

Kuwedzera Kusimba Nekuvandudza kushanda, kuchengetedza mvura, uye kunamatira zvinhu zvesimende-based materials, HEC inogona kubatsira kuwedzera kusimba kwavo kwese. Cement-based materials iyo inovandudzwa neHEC inogona kuva nehupenyu hurefu hwebasa uye inoda zvishoma kugadzirisa nekugadzirisa nekufamba kwenguva.

Uye zvakare, HEC inogona zvakare kuvandudza kuramba kwesimende-yakavakirwa zvinhu kune akasiyana siyana ezvakatipoteredza zvinhu, senge mamiriro ekunze, kutonhora-kutenderera kutenderera, uye kuratidzwa kwemakemikari. Izvi zvinogona kuita kuti dzive dzakanyanya kukodzera kushandiswa munzvimbo dzakaoma uye kuvandudza kushanda kwavo kwese uye hupenyu hurefu.

Mhedziso HEC inogoneka uye inoshanda simende yekuwedzera iyo inogona kuvandudza maitiro ekuita zvesimende-based zvinhu. Kugona kwayo kusimudzira kushanda, kuchengetedza mvura, kunamatira, uye kusimba kunoita kuti ive chishandiso chakakosha kuindasitiri yekuvaka.

Kana iwe uchifarira kushandisa HEC sekuwedzera simende, zvakakosha kushanda nemutengesi ane mukurumbira kuti uve nechokwadi chekuti uri kuwana chigadzirwa chemhando yepamusoro chinoenderana nezvido zvako uye zvaunoda. Kima Chemical inogadzira uye mutengesi wezvigadzirwa zve cellulose ether, zvinosanganisira HEC, uye vanopa huwandu hwemagiredhi uye zvakatemwa kuti zvisangane nezvinodiwa zvakasiyana zveindasitiri yekuvaka.
