Qhov sib txawv tseem ceeb ntawm lubricant glidant thiab anti adherent yog tias cov roj nplua nyeem txo cov kev sib txhuam thaum lub glidant txhawb nqa cov dej ntws ntawm cov hmoov whereas cov tshuaj tiv thaiv adherent muab cov khoom tsis-sticking.
Txawm hais tias lo lus lubricants muaj ntau daim ntawv thov nyob rau hauv ntau zaus, peb tab tom tham txog kev siv lo lus no hauv tshuaj chemistry. Lubricants, glidants thiab anti-adherents yog cov khoom uas peb siv nyob rau hauv kev lag luam kws tshuaj thaum tsim ib ntsiav tshuaj; ua tshuaj.
Lubricant yog dab tsi?
Lubricants yog cov khoom uas peb siv hauv cov ntsiav tshuaj thiab cov tshuaj ntsiav tshuaj kom txo tau kev sib txhuam. Ntawd yog, cov khoom no tuaj yeem txo qhov kev sib txhuam ntawm cov khoom uas peb siv los ua cov ntsiav tshuaj thaum compression. Ntxiv mus, cov khoom no tuaj yeem txo qhov kev sib txhuam ntawm cov phab ntsa ntawm cov ntsiav tshuaj thiab cov phab ntsa ntawm cov kab noj hniav uas peb tsim cov ntsiav tshuaj. Cov khoom no tuaj yeem tsim lub tsho tiv no nyob ib puag ncig txhua granule uas peb siv hauv qhov kev tsim khoom no. Tsis tas li ntawd, lub tsho tiv no tsim cov nyhuv tau txuas mus rau ntawm cov ntsiav tshuaj nto ib yam nkaus.
Txawm li cas los xij, cov roj nplaum no qhia qee qhov tsis zoo thiab. Piv txwv li, nws txo lub zog tensile ntawm cov ntsiav tshuaj los ntawm kev cuam tshuam nrog kev sib txuas ntawm cov khoom ntawm cov ntsiav tshuaj. Ntxiv mus, ncua lub sij hawm disintegration thiab dissolution ib yam nkaus. Qhov no txhais tau tias cov roj nplua nyeem tuaj yeem muab cov khoom tsis muaj dej tsis zoo rau cov ntsiav tshuaj. Ntxiv rau qhov ntawd, qhov concentration ntawm cov khoom no yuav tsum tsis pub tshaj 1% thiaj li yuav tau txais qhov siab tshaj plaws ntws. Qee qhov piv txwv ntawm cov roj nplua nyeem uas peb siv hauv kev tsim tshuaj yog stearic acid thiab calcium lossis magnesium ntsev ntawm stearic acid.
Glidant yog dab tsi?
Glidants yog cov khoom uas peb siv los ua kom cov dej ntws ntawm cov hmoov. Qhov ntawd txhais tau hais tias nws txhawb nqa qhov ntws ntawm cov ntsiav tshuaj granules (los yog hmoov). Nws ua li ntawd los ntawm kev txo cov kev sib txhuam ntawm cov granules. Txawm li cas los xij, cov nyhuv ntawm cov tshuaj no nyob ntawm cov duab thiab qhov loj ntawm granules thiab glidants.
Daim duab 01: ntsiav tshuaj thiab Capsules
Feem ntau, cov ntaub ntawv hydrophilic ua tau zoo dua ntawm hydrophilic granules thiab rov ua dua. Cov tebchaw no ua kom cov ndlwg ntawm cov granules ntawm ib qho formulation mus txog qhov zoo tshaj plaws concentration. Yog hais tias qhov concentration ntawm cov glidant tshaj qhov zoo tshaj plaws concentration, nws yuav ua rau ib tug luag hauj lwm uas txo tus nqi txaus. Qee cov glidants uas peb siv hauv kev lag luam tshuaj yog talc, starch, colloidal silica, silicates, thiab lwm yam. Ntawm lawv, cov tsoos glidant yog talc.
Anti Adherent yog dab tsi?
Anti-adherents yog cov khoom uas tuaj yeem tiv thaiv cov ntsiav tshuaj los ntawm nws cov khoom adhesion. Yog li ntawd peb tuaj yeem hu lawv "cov neeg ua haujlwm tsis-sticking". Cov tshuaj no tuaj yeem zam qhov adhesion ntawm cov ntsiav tshuaj nto rau ntawm phab ntsa ntawm kab noj hniav uas peb tsim cov ntsiav tshuaj. Raws li kev tawm tsam, peb tuaj yeem siv dej-insoluble lubricants xws li magnesium stearate, talc thiab starch.
Qhov txawv ntawm Lubricant Glidant thiab Anti Adherent yog dab tsi?
Lubricants yog cov khoom uas peb siv hauv cov ntsiav tshuaj thiab cov tshuaj ntsiav tshuaj kom txo tau kev sib txhuam. Qhov tseem ceeb tshaj, cov tshuaj no txo cov kev sib txhuam ntawm cov khoom uas peb siv los ua cov ntsiav tshuaj thaum compression. Glidants yog cov khoom uas peb siv los ua kom cov dej ntws ntawm cov hmoov. Ntxiv mus, nws nce tus nqi ntws ntawm cov granules ntawm cov hmoov uas peb siv rau cov ntsiav tshuaj tsim. Anti-adherents yog cov khoom uas tuaj yeem tiv thaiv cov ntsiav tshuaj los ntawm nws cov khoom adhesion. Qhov tseem ceeb, cov tshuaj no zam cov adhesion ntawm cov ntsiav tshuaj nto rau ntawm phab ntsa ntawm kab noj hniav uas peb tsim cov ntsiav tshuaj. Cov nram qab no infographic nthuav tawm qhov sib txawv ntawm lubricant glidant thiab anti adherent nyob rau hauv daim ntawv tabular.
Summary – Lubricant Glidant vs Anti Adherent
Muaj ntau yam khoom uas peb siv los tsim cov ntsiav tshuaj hauv kev lag luam kws tshuaj xws li roj nplua nyeem, glidants thiab anti-adherents. Qhov sib txawv ntawm lubricant glidant thiab anti adherent yog tias lubricants txo cov kev sib txhuam thaum glidants txhawb lub flowability ntawm cov hmoov whereas anti adherents muab cov khoom tsis-sticking.
