Ukuphucula ukusebenza kwelebhoratri nge-tubing ye-Peek: Isikhokelo esibanzi

Kwindawo yokwenyani ye-chromatography ye-chromatography e-chromatography (HPLC) kunye nezinye iindlela zobuchule bokuhlalutya, ukhetho lwetyhubhu lungayichaphazela kakhulu ukuchaneka kunye nokuthembeka kweziphumo. I-Polyteether Ether Ketone (Pek) ityhubhu ivele njengezinto ezikhethiweyo, zibonelela ngokudityaniswa kwamandla omatshini kunye nokuxhathisa kwamachiza. Eli nqaku livuka kwiingenelo zeI-Teek Buuting, ngakumbi i-1/16 i-Outer Seameter (OD) eyahlukileyo, kwaye inike isikhokelo ekukhetheni idaya elingaphakathi elingaphakathi (i-ID) yezicelo ezahlukeneyo.

Ukubaluleka kokukhetha ityhubhu kwizicelo zohlalutyo

Ukukhetha ityhubhu elungileyo kubaluleke kakhulu ekusetani uhlalutyo. Iqinisekisa:

•Ukuhambelana kwamachili: Thintela ukuphendula phakathi kwezinto ezibonakalayo kunye nezinyibilikisi okanye iisampulu.

•Ukunganyangeki koxinzelelo: Ukumelana noxinzelelo lwendlela yokusebenza yenkqubo ngaphandle kwengqwalaselo.

•Ukuchaneka kwe: Gcina amaxabiso okuhamba okuhamba kwaye inciphise imiqulu efileyo.

Izibonelelo ze-Peek Bubhali

I-Peek Tiub imele ngenxa yayo:

•Amandla amakhulu oMatshini: Iyakwazi ukucinezelwa okukhulu kwi-400 bar, iyenza ilungele izicelo zoxinzelelo oluphezulu.

•Ukuxhathisa iikhemikhali: I-Inert ininzi izicoci, ukunciphisa umngcipheko wongcoliseko kunye nokuqinisekisa ukuthembeka kweziphumo zohlalutyo.

•Uzinzo lwe-thermal: Ngendawo yokunyibilika engama-350 ° C, ityhubhu ye-Peek ihlala izinzile phantsi kwamaqondo obushushu aphakamileyo.

•Ukucofa: Ilungele izicelo ezibandakanya iisampulu zebhayoloji, ziqinisekisa ukuba akukho ndlela imbi.

Ukuqonda 1/16 "I-OD Peek Bubhali

I-1/16 ye-OD lubukhulu obuqhelekileyo kwiinkqubo ze-HLLC, ezihambelana nezixhobo kunye neziqhoboshelo. Lo mgangatho wobume lula kudityaniswa kwenkqubo kunye nolondolozo. Ukukhetha ububanzi be-iniameter (i-ID) yinto ebaluleke kakhulu, njengoko iphembelela amaxabiso okuhamba kunye noxinzelelo lwenkqubo.

Ukukhetha ububanzi be-iphakathi efanelekileyo

I-tuby tuby ifumaneka kwii-ID ezininzi, nganye iphela kwiimfuno ezithile zokuhamba:

•I-0.13 mm (ibomvu): Ilungele izicelo zokuhamba okuncinci apho ulawulo oluchanekileyo lubalulekile.

•I-0.18 mm (yendalo): Ifanelekile ukuba irhafu ephakathi yokuhamba, ukulinganisa uxinzelelo kunye nokuhamba.

•I-0,25 mm (iblowu): Isetyenziswa rhoqo kwizicelo ezisemgangathweni ze-HLPC.

•I-0.50 mm i-ID (ye-tyheli): Ixhasa amaxabiso aphezulu okuhamba, efanelekileyo kwi-chromatography ye-chromatography.

•I-0.75 mm (iluhlaza): Isetyenziswe kwizicelo ezifuna ukuhamba okukhulu ngaphandle kokwakha uxinzelelo olubalulekileyo.

•I-1.0 mm (ngwevu): Ilungele ukusetyenziswa okuphezulu kakhulu, ukunciphisa umva.

Xa ukhetha i-ID, qwalasela i-viscomosity yeZicingela zakho, ireyithi yokuhamba oyifunayo, kunye nemida yoxinzelelo lwenkqubo.

Izenzo ezilungileyo zokusebenzisa i-tubing ye-peek

Ukukhulisa izibonelelo ze-Peek Tiub:

•Khusela izinyibilikisi ezithile: I-Peek ayihambelani ne-sulfuric kunye ne-nitric acids. Ukongeza, izinyibilikiswe njenge-DMSO, dichloromethane, kwaye i-thf inokubangela ukwanda kwetyhubhu. Yiba nononophelo xa usebenzisa ezi zinyibilikisi.

•Iindlela ezifanelekileyo zokuchebaSebenzisa amasikisi afanelekileyo okuqinisekisa ukuba icocekile, ukunqunyulwa okungapheliyo, ukugcina imeko efanelekileyo yokutywina kunye nokuhamba kokuhamba.

•Ukuhlolwa rhoqo: Ngamaxesha athile ukhangela imiqondiso yokunxiba, njengokuqina komphezulu okanye ukungqinelana, ukuthintela ukusilela kwenkqubo.

Ukuqukumbela

I-Peek Tiub, ngakumbi "i-1/16 i-OD eyahlukileyo, inikezela isisombululo esinokuthenjwa nesiguquguqukayo kwizicelo ezahlukeneyo zohlalutyo. Ukudityaniswa kwayo okwahlukileyo, ukuxhathisa kwemichiza, kunye nokuzinza kwe-thermal kwenza ukuba icandelo elixabisekileyo kulo naluphi na useto lwelebhu. Ngokukhetha ububanzi bobuchwephesha obufanelekileyo kunye nokubambelela kwiindlela ezilungileyo, iilebhu zingayiphucula intsebenzo yazo yohlalutyo kunye neziphumo ezichanekileyo, ezichanekileyo.

Kwizilungiso eziphezulu ze-Peek ezisemgangathweni ezilungiselelwe iimfuno zakho zelebhu, nxibelelanaI-ChrosirNamhlanje. Iingcali zethu zikulungele ukukunceda ukwenzela ukujongwa kwendlela ohlalutyo.
