Chimwe chinhu chiri kutariswa zvakanyanya munyika yemakemikari nemaindasitiri is stearic acid poda.
Stearic acid poda ichena crystalline poda isinganhuhwi uye isinganakidze. Kemikari, ine kugadzikana kwakanaka uye kugadzikana kwekupisa uye haibvumirwi nemakemikari, iyo inobvumira kuchengetedza zvinhu zvayo munzvimbo dzakasiyana-siyana. Mukuwedzera, stearic acid poda ine zvimwe zvekuzora uye hydrophobic zvivakwa, uye zvivakwa izvi zvinoisa hwaro hwekushandiswa kwayo munzvimbo dzakasiyana.
Stearic acid poda inobva kwakasiyana siyana. Inonyanya kutorwa kubva kumhuka chaiyo nemafuta emiriwo nemafuta, akadai semafuta emichindwe uye tallow. Kuburikidza nenhevedzano yemakemikari kugadzirisa uye kukwenenzvera, iwo mafuta asidhi ari mumafuta aya nemafuta anopatsanurwa uye anocheneswa kuti pakupedzisira awane stearic acid hupfu. Iyi nzira yekutsvagisa inovimbisa kugadzikana kwekupa kwayo uye inoderedza kukanganisa kwayo kwezvakatipoteredza kusvika pamwero wakati.
Stearic acid poda inokunda kana zvasvika pakubudirira. Chekutanga, irubricant yakanakisa inogona kuderedza kukweshera uye kupfeka, uye kugadzirisa kushanda zvakanaka uye hupenyu hwesevhisi hwemuchina nemidziyo. Muindasitiri yemapurasitiki, kuwedzera kweStearic acid poda kunogona kuvandudza mashandiro epurasitiki, kuita kuti zvive nyore kuumba, uye kuwedzera kupedzisa kwepamusoro uye kuchinjika kwezvigadzirwa zvepurasitiki. Chechipiri, stearic acid hupfu zvakare ine emulsifying uye kuparadzira mhedzisiro, uye inoshandiswa zvakanyanya muzvizora nemishonga. Inogona kubatsira zvakasiyana-siyana zvinosanganisa kusanganisa zvakaenzana uye kuvandudza kunaka uye kugadzikana kwezvigadzirwa. Pamusoro pezvo, inoitawo basa rakakosha muindasitiri yerabha, iyo inogona kuwedzera kusimba uye abrasion kuramba kwerabha.
Stearic acid poda inoshandiswa mune zvakasiyana siyana zvekushandisa.
Muindasitiri yepurasitiki, chinhu chinodiwa chekuwedzera. Semuenzaniso, mukugadzirwa kwepolyethylene (PE) uye polypropylene (PP), stearic acid poda inovandudza kuyerera uye kuburitsa zvinhu zvemapurasitiki, zvichikonzera kuwedzera kubereka uye kunaka kwechigadzirwa. Mukugadzirisa kwepolystyrene (PS) uye polyvinyl chloride (PVC), inowedzera kuoma uye kupikisa kupisa kwemapurasitiki, kuwedzera huwandu hwavo hwekushandisa.
Stearic acid poda yakakoshawo muzvizora, kwainowanzo shandiswa semulsifier uye consistency regulator mune zvigadzirwa zvekuchengetedza ganda senge makirimu, lotions uye lipsticks, kuita kuti kuumbwa kwechigadzirwa kuve kwakafanana uye kugadzikana. Mune zvizoro zvemavara, zvakadai semumvuri weziso uye nheyo, zvinobatsira kuvandudza kunamatira uye hupenyu hurefu hwechigadzirwa, zvichiita kuti chiwedzere kunaka.
Indasitiri yemishonga inotorawo zvizere zvizere zvezvinhu zve stearic acid powder. Mukugadzirwa kwemishonga, inogona kushandiswa sechinhu chinobatsira uye mafuta ekuzora kubatsira mushonga kuti unyatsoumbwa uye usunungurwe, uye kuvandudza bioavailability yemushonga. Zvichakadaro, mune mamwe macapsule formulations, stearic acid poda inogona kuitawo basa mukutsaura nekudzivirira mushonga.
Muindasitiri yerabha, stearic acid poda inogona kusimudzira vulcanisation process yerabha uye kugadzirisa muchinjika-wekubatanidza density yerabha, nekudaro ichiwedzera michina zvivakwa uye kuchembera kuramba kwezvigadzirwa zverabha. Angave matayi, zvisimbiso zverabha kana mabhandi ekutakura erabha, stearic acid poda inopa mupiro wakakosha mukuvandudzwa kwemhando yavo nekushanda.
Pamusoro pezvo, stearic acid poda ine zvakakosha mashandisirwo mumaindasitiri emucheka, yekupotera uye inki. Muindasitiri yemachira, inogona kushandiswa seinopfavisa uye inodzinga mvura kuvandudza kunzwa uye kuita kwemachira. Mune majasi nemainki, inovandudza kupararira uye kugadzikana kwemavara uye inosimudzira kupenya uye kunamatira kwekupfeka.
Mukupedzisa, stearic acid poda inoita basa rakakosha muindasitiri yemazuva ano uye hupenyu nehunhu hwayo hwakasiyana, kwakasiyana masosi, kunoshamisa kushanda uye kuwanda kwekushandisa.
