Alaabta caadiga ah ee caagga ah ee la isticmaalo ee shaybaarada

Waxaa jira alaabooyin tijaabo ah oo kala duwan.Marka laga soo tago alaabada quraaradaha, kuwa ugu badan ee la isticmaalo waa kuwa caag ah.Haddaba ma garanaysaa waxyaalaha ay ka samaysan yihiin caagadaha loo isticmaalo nolol maalmeedka?Waa maxay sifooyinka?Sidee loo doortaa?Aan mid mid ugu jawaabno sida hoos ku qoran.

Alaabta caagga ah ee lagu isticmaalo shaybaadhka ayaa u badantalooyinka pipette, tuubooyinka centrifuge,Taarikada PCR, saxannada dhaqanka unugga/taarikada/ dhalooyinka, cryovials, iwm. Inta badan talooyinka pipette-ka, taarikada PCR, cryovials iyo waxyaabaha kale ee la isticmaalo waa PP.Maad (polypropylene),isticmaalka dhaqanka unuggaguud ahaan waxay ka samaysan yihiin PS (polystyrene), caarada dhaqanka unuggu waxay ka samaysan yihiin PC (polycarbonate) ama PETG (polyethylene terephthalate copolymer).

1. Polystyrene (PS)

Waxay leedahay gudbinta iftiinka wanaagsan oo aan sun ahayn, oo leh gudbinta iftiinka 90%.Waxay leedahay caabbinta kiimikada wanaagsan ee xalalka aqueous, laakiin caabbinta liidata ee dareerayaasha.Waxay leedahay faa'iidooyin qiimo gaar ah marka loo eego balaastikada kale.Daah-furnaan sare iyo qallafsanaan sare.

Alaabooyinka PS aad bay u jajaban yihiin heerkulka qolka waxayna u nugul yihiin inay dillaacaan ama jabaan marka la rido.Heerkulka isticmaalka joogtada ah waa qiyaastii 60 ° C, iyo heerkulka isticmaalka ugu badan waa inuusan dhaafin 80 ° C.Laguma nadiifin karo heerkul sare iyo cadaadis sare oo ah 121°C.Waxaad dooran kartaa jeermis-dilista iftiinka elektarooniga ah ama jeermiska kiimikada.

Dhalooyinka dhaqanka unugga ee Shandong Labio, suxuunta dhaqanka unugga, taarikada dhaqanka unugga, iyo pipette-yada serological waxay dhamaantood ka samaysan yihiin polystyrene (PS).

2. Polypropylene (PP)

Qaab dhismeedka polypropylene (PP) wuxuu la mid yahay polyetylen (PE).Waa resin thermoplastic oo laga sameeyay polymerization of propylene.Badanaa waa mid aan midab lahayn oo adag, aan ur lahayn oo aan sun ahayn.Faa'iidada ugu weyn ee ay leedahay waa in lagu isticmaali karo heerkul sare iyo cadaadis 121 ° C.Jeermiska.

Polypropylene (PP) waxay leedahay sifooyin farsamo oo wanaagsan iyo iska caabin kiimikaad.Waxay u adkeysan kartaa daxalka asiidhka, alkalis, dareeraha milixda iyo dareerayaasha organic kala duwan ee ka hooseeya 80 ° C.Waxay leedahay adkaysi, xoog iyo iska caabin kulayl ka fiican marka loo eego polyetylen (PE).;Marka la eego iska caabinta heerkulka, PP sidoo kale wuu ka sarreeyaa PE.Sidaa darteed, markaad u baahan tahay gudbinta iftiinka ama indho-indheynta fudud, ama caabbinta cadaadiska sare ama isticmaalka heerkulka, waxaad dooran kartaa isticmaalka PP.

3. Polycarbonate (PC)

Waxay leedahay adayg wanaagsan iyo qallafsanaan, si sahal ah uma jabna, waxayna leedahay caabbinta kulaylka iyo caabbinta shucaaca labadaba.Waxay buuxisaa shuruudaha heerkulka sare iyo nadiifinta cadaadiska sare iyo habka shucaaca tamarta sare ee goobta biomedical.Polycarbonate (PC) inta badan waxaa lagu arki karaa alaabooyinka qaarkood, sidasanduuqyada qaboojintaiyodhalooyinka erlenmeyer.

4. Polyethylene (PE)

Nooc ka mid ah resin thermoplastic, oo aan ur lahayn, aan sun ahayn, ayaa dareemaya sidii shamac, wuxuu leeyahay iska caabin heerkul hooseeya oo aad u fiican (heerkulka ugu hooseeya wuxuu gaari karaa -100 ~ -70 ° C), wuxuuna si fudud u jilciyaa heerkul sare.Waxay leedahay xasillooni kiimiko oo wanaagsan sababtoo ah molecules-yada polymer waxay ku xiran yihiin kaarboon-kaarboon hal bond waxayna iska caabin karaan nabaad-guurka inta badan asiidhyada iyo alkaliska (aan u adkaysanaynin asiidhyada leh sifooyinka oksaydheynta).

Marka la soo koobo, polypropylene (PP) iyo polyetylen (PE) ayaa ah noocyada ugu badan ee balaastigga ah ee shaybaarada.Markaad dooranayso alaabta la isticmaalo, waxaad badanaa dooran kartaa labadan haddii aysan jirin baahiyo gaar ah.Haddii ay jiraan shuruudo loogu talagalay iska caabbinta heerkulka sare iyo heerkulka sare iyo nadiifinta cadaadiska sare, waxaad dooran kartaa alaabooyinka ka samaysan polypropylene (PP);haddii aad leedahay shuruudo loogu talagalay waxqabadka heerkulka hooseeya, waxaad dooran kartaa polyetylen (PE);iyo agabka la isticmaalo ee dhaqanka unuggu badidood waxa ay ka samaysan yihiin polystyrene (PS).
