Hydroxypropyl starch ether (HPS)uyecellulose etherndiwo maviri akajairika ekuvaka makemikari ekuwedzera, anoshandiswa zvakanyanya mukuvaka zvinhu, sedhaka, putty hupfu, coatings, etc. Kunyange zvazvo vane kufanana mune zvimwe zvinhu, kune misiyano yakakura muzvinhu zvakawanda senge raw material sources, makemikari zvimiro, zvinhu zvemuviri. , maitiro ekushandisa, uye mari.
1. Raw zvinhu zvinyorwa uye chimiro chemakemikari
Hydroxypropyl starch ether (HPS)
HPS yakavakirwa pachisikigo starch uye inowanikwa kuburikidza ne etherification modification reaction. Zvishongo zvayo zvakakosha chibage, gorosi, mbatatisi uye zvimwe zvinomera zvakasikwa. Starch molecules inoumbwa neglucose units yakabatanidzwa ne-α-1,4-glycosidic bonds uye shoma shoma ye-α-1,6-glycosidic bonds. Mushure me hydroxypropylation, boka re hydrophilic hydroxypropyl rinounzwa muHPS molecular chimiro, ichipa kumwe kukora, kuchengetedza mvura uye kugadzirisa mabasa.
cellulose ether
Cellulose ethers inotorwa kubva kune yakasikwa cellulose, senge donje kana huni. Cellulose inoumbwa nemayuniti eglucose akabatanidzwa ne β-1,4-glycosidic bonds. Common cellulose ethers dzinosanganisira hydroxypropyl methylcellulose (HPMC), methylcellulose (MC), hydroxyethyl cellulose (HEC), etc. Izvi zvinosanganiswa zvinounza zvakasiyana-siyana kuburikidza nekuita kwe etherification uye zvine kugadzikana kwemakemikari yakakwirira uye zvinhu zvemuviri.
2. Zvinhu zvemuviri
Kuita maitiro eHPS
Kukora: HPS ine kunaka kukora mhedzisiro, asi kana ichienzaniswa neselulosi ether, iko kukora kwayo kushoma zvishoma.
Kuchengetedzwa kwemvura: HPS ine mwero wekuchengetedza mvura uye inokodzera yakaderera kusvika yepakati-renji zvekuvaka.
Kushanda: HPS inogona kuvandudza kushanda kwedhaka uye kuderedza sagging panguva yekuvaka.
Kuramba tembiricha: HPS inonzwa zvakanyanya kune tembiricha uye inokanganiswa zvakanyanya neambient tembiricha.
Kuita maitiro e cellulose ethers
Kukora: Cellulose ether ine simba rekukora uye inogona kuwedzera zvakanyanya viscosity yedhaka kana putty.
Kuchengetedzwa kwemvura: Cellulose ether ine yakanakisa kuchengetedza mvura, kunyanya munzvimbo dzekushisa kwepamusoro, iyo inogona kuwedzera nguva yekuvhurwa kwedhaka uye kudzivirira kurasikirwa kwemvura yakawandisa.
Kushanda: Cellulose ether yakanakisa mukuvandudza kushanda uye inogona kuderedza zvinobudirira matambudziko akadai sekutsemuka uye upfu.
Kuramba tembiricha: Cellulose ether ine kuchinjika kwakasimba kune tembiricha shanduko uye kuita kwakagadzikana.
3. Maitiro ekushandisa
Application effect yeHPS
Mumatope akaoma, HPS inonyanya kuita basa rekuvandudza kushanda, kuvandudza kuchengetedza kwemvura, uye kuderedza delamination uye kupatsanura. Iyo ine hupfumi uye yakakodzera kushandiswa mumamiriro ezvinhu ane yakakwira mutengo wekutonga zvinodiwa, seyakajairwa yemukati madziro putty poda, pasi inoisa dhaka, nezvimwe.
Maitiro ekushandiswa kwe cellulose ether
Cellulose ethersanoshandiswa zvakanyanya mumatare epamusoro-anoshanda, anonamira mataira, gypsum-based materials uye ekunze emadziro ekudzivirira masisitimu. Kuwedzera kwayo kwepamusoro uye kuchengetwa kwemvura zvivakwa zvinogona kuvandudza zvakanyanya simba rekubatanidza uye anti-slip performance yezvinhu, uye inonyanya kukodzera mapurojekiti ane zvakakwirira zvinodikanwa pakuita kwekuvaka uye kupedzwa kwemhando yechigadzirwa.
4. Mutengo uye kuchengetedzwa kwezvakatipoteredza
mutengo:
HPS ine mutengo wakaderera uye yakakodzera kushandiswa mumisika isingatengi. Cellulose ethers inodhura, asi ine mashandiro akanaka uye inodhura-inoshanda mukuda mapurojekiti ekuvaka.
Kuchengetedza kwezvakatipoteredza:
Zvose zviri zviviri zvakatorwa kubva kuzvinhu zvechisikigo uye zvine maitiro akanaka ezvakatipoteredza. Nekudaro, nekuti mashoma emakemikari reagents anopedzwa mukugadzirwa kweHPS, mutoro wayo wezvakatipoteredza unogona kunge wakadzikira.
5. Sarudzo hwaro
Performance zvinodiwa: Kana uine zvinodiwa zvakakwirira zvekukora uye kuchengetedza mvura, unofanirwa kusarudza cellulose ether; kune zvinhu zvisingadhuri asi zvinoda kuvandudzwa kwekushanda, unogona kufunga nezvekushandisa HPS.
Mamiriro ekushandiswa: Kuvakwa kwepamusoro-kupisa, kuvhara kwekunze kwemadziro, kunamatira tile uye mamwe mamiriro ezvinhu anoda rubatsiro rwepamusoro-soro anonyanya kukodzera cellulose ether; kune yakajairwa yemukati madziro putty kana basic dhaka, HPS inogona kupa ehupfumi uye inoshanda mhinduro.
Hydroxypropyl starch etheruyecellulose ether mumwe nemumwe ane zvazvakanakira uye vanoita mabasa akasiyana mukuvaka. Sarudzo yacho inofanirwa kutariswa zvizere zvichienderana nezvinodiwa zvekuita, kudzora mutengo, nharaunda yekuvaka uye zvimwe zvinhu zveiyo purojekiti kuti uwane iyo yakanyanya kushandisa mhedzisiro.
