Izidumbu zelebhu zingena kwiintlobo ezahlukeneyo, kwaye akukho nto ithile inokuhlangabezana nazo zonke iimfuno zovavanyo. Ke, uyazi ukuba zeziphi izinto ezisetyenziswayo ezisetyenziswayo kwiplastiki? Kwaye yintoni umahluko kwiipropathi zabo zomzimba kunye nekhemikhali? Ngoku siza kuphendula le mibuzo ngenye ngezantsi.

I-PP (iPolyproplene)

I-Polypropylene, efinyezwe njenge-PP, yipolymer eyenziwe nge-polymering ye-proplene. Ihlala i-translucent, enemibala eqinileyo, engenamabala, kwaye ingabinetyhefu. Inozinzo oluhle lobushushu kwaye inokuthi isebenze kwi-sterilizations kubushushu obuphakamileyo kunye noxinzelelo lwe-121 ° C. Nangona kunjalo, iba brittle kumaqondo obushushu asezantsi (ngaphantsi kwe-4 ° C) kwaye uthanda ukuqhekeza okanye ukwaphula xa kuphoswa kubude.

I-Polypropylene (PP) ibonisa iipropathi ezigqwesileyo kunye nokuchasana nemichiza. Inokumelana nokulungela i-AIDDs, iziseko, izisombululo zetyuwa, kunye nezinyibilikisi ezahlukeneyo eziphantsi kwe-80 ° C. Xa kuthelekiswa ne-polyethylene (PE), i-PP inika ukuqina okuthe kratya, amandla, kunye nokumelana nobushushu. Ke ngoko, xa izinto ezinokuthethwa zifuna ukuthunyelwa ukukhanya okanye ukuqaphela okulula, kunye namandla aphezulu oxinzelelo okanye ukunganyangeki kobushushu, izixhobo ze-PP zinokukhethwa.

Izinto ezinokuthethwa zii-tyrifuge tubes, ii-pubc tubes, i-PCR 96-Iibhotile ze-Regant, ii-tuby ezigcina, kunye neengcebiso zepabhu zonke zenziwe ngePolypropylene njengezixhobo ezibukhali.

I-PS (i-polystrene)

I-Polystyrene (Ps), idityaniswe nge-polymerication ye-rayrene ye-styrene, yi-thermoplastic engenabala kwaye ibonakale i-thermoistic kunye nokukhanya okugqithisileyo ukuya kuthi ga kwi-90%. I-PS ibonisa ingqongqo engqongqo, engabuthukini, kunye nozinzo olunamandla, kwaye lunokuchasana nemichiza elungileyo kwizisombululo zemozulu kodwa ukumelana nokungaxhathisi. Iimveliso ze-PS zine-brittle kubushushu begumbi kwaye zithambekele ekuqhekezeni okanye zokuqhekeza xa zisiwe. Elona qondo lokusebenza liphezulu akufuneki lidlule kwi-80 ° C, kwaye ayinakukwazi ukwenza intsholongwane kumaqondo obushushu aphezulu kunye noxinzelelo lwe-121 ° C. Endaweni yoko, ukwenziwa kwe-eleam ye-eleam okanye intsholongwane inokukhethwa.

I-enzyme-ilebheli, inkcubeko yokuthengisa iiseli, kunye nemibhobho yeserum yonke yenziwa nge-polystyrene (i-PS) njengezixhobo zabo eziluhlaza.

I-PE (POLYTHTHTHIN)

I-Polythylene, ifinyezwe njenge-PE, yi-thermoplastic relin efunyenwe kwi-polymering ye-polymeners. Yinto engekho buhlungu, engenabunzi, kwaye inomsindo. I-PE ibonisa ukunganyangeki kobushushu obuphantsi kakhulu (kunye nobushushu obungenasiphelo obuvela kwi-100 ukuya kwi-700 ° C). Iba ithambile kumaqondo obushushu aphezulu kwaye i-opaque.

Njengenye iPolyoolefin, i-Polythylene sisixhobo se-Inest Foot kunye nozinzo lweekhemikhali ezifanelekileyo. Ngenxa ye-carbon-carbon enye ngaphakathi kwe-polymer molekyuli, inokuxhathisa ukhukuliseko lwe-acedies kunye ne-acetone Acid, njl njl. Njl.

Iibhotile zokuqala, imibhobho, iibhotile, kunye nezinye izinto ezinokusetyenziswa ziqhele okwenziwa yi-polyethylene (pe).

I-PC (i-polycarbonate)

I-Polycarbonate, ekwabizwa ngokuba yiplastiki yePC, i-polymer eneqela le-carbonate kwi-molecular thein yayo. Ibonisa ubunzima obulungileyo kunye nobunkunkqele, busenza inyange ukophula. Ukongeza, inoxhathiso lobushushu kunye nokunganyangeki kwe-radiation, ukuhlangabezana neemfuno zobushushu obuphakathi, i-steredical ye-right ephezulu kunye ne-radiation ephezulu kwintsimi ye-biomedical.

I-Polycarbonate ayichasanga kwi-acid ebuthathaka, iziseko ezibuthathaka, kunye neoyile engathathi cala. Nangona kunjalo, ayixhathisi ukunyangwa kwe-Ultraviolet kunye neziseko ezomeleleyo.

Iibhokisi zokukhulula, ezinye ii-magnetic scings, kunye ne-erlenmeyer flasks zenziwa ngezinto zePolycarbonate (PC).

Oku kungasentla kuchaza izixhobo ezininzi ezisetyenziswayo ezisetyenziselwa ukutya kwelebhu. Ngokubanzi, ezi zixhobo zinokukhethwa ngaphandle kweemfuno ezizodwa. Ukuba uvavanyo lunemifuno ethile, umntu unokucinga ngokukhetha izixhobo ezihlangabezana neemfuno okanye aguqule izixhobo ezikhoyo ukufezekisa iipropathi eziyimfuneko.
