Zaɓin da aikace-aikacen kwalabe na reagent PP/HDPE

Za a iya amfani da kwalabe na reagent don ajiya da jigilar sinadarai na musamman, abubuwan ganowa, samfuran halitta, reagents, adhesives da magungunan dabbobi.A halin yanzu, kayan kwalabe na reagent galibi gilashi ne da filastik, amma gilashin yana da rauni kuma tsaftacewa yana da wahala.Saboda haka, da filastik reagent kwalabe tare da karfi inji yi da acid da alkali lalata sun sannu a hankali sun zama mashahurin zabi a kasuwa.Babban yawa polyethylene (HDPE) da polypropylene (PP) abubuwa ne na filastik da aka saba amfani da su.Ta yaya za mu zaɓi waɗannan nau'ikan kwalabe biyu na reagent?

1. Haƙurin zafi

HDPE abu yana da juriya ga ƙananan zafin jiki da zafin jiki mai girma, don haka lokacin da ake buƙatar ajiyar ƙananan zafin jiki, an zaɓi ƙarin kwalabe na reagent da aka yi da kayan HDPE;PP abu yana da tsayayya ga babban zafin jiki da ƙananan zafin jiki, lokacin da ake buƙatar babban zafin jiki na autoclave, ya kamata a zaɓi kwalban reagent na kayan PP.

2.Chemical juriya

Dukansu HDPE abu da PP abu ne acid-alkali resistant, amma HDPE abu ne mafi alhẽri daga PP abu dangane da hadawan abu da iskar shaka juriya.Saboda haka, a cikin ajiya na oxidizing reagents, kamar benzene zobba, n-hexane, chlorinated hydrocarbons da sauran Organic kaushi, HDPE abu ya kamata a zaba.

3.Hanyar hana haihuwa

A cikin hanyar haifuwa, bambanci tsakanin kayan HDPE da kayan PP shine cewa PP za a iya haifuwa a babban zafin jiki da matsa lamba, kuma HDPE ba zai iya ba.Dukansu HDPE da PP kayan za a iya haifuwa ta EO, sakawa a iska mai guba (ana buƙatar PP mai iska mai iska, in ba haka ba zai zama rawaya) da disinfectant.

4.Launi da bayyana gaskiya

Launi na reagent kwalabe ne kullum na halitta (translucent) ko launin ruwan kasa, launin ruwan kasa kwalabe da kyau kwarai shading sakamako, za a iya amfani da su adana sinadaran reagents da aka sauƙi bazu da haske, kamar nitric acid, azurfa nitrate, azurfa hydroxide, chlorine ruwa. da sauransu, ana amfani da kwalabe na halitta don adana reagents na gabaɗaya.Saboda tasirin tsarin kwayoyin halitta, kayan PP sun fi dacewa fiye da kayan HDPE, wanda ya fi dacewa don lura da yanayin kayan da aka adana a cikin kwalban.

Ko yana da PP abu ko HDPE abu reagent kwalban, bisa ga kayan aiki halaye, akwai dace da irin sinadaran reagents, don haka halaye na sinadaran reagents ya kamata a yi la'akari da lokacin da zabar reagent kwalban.
