Isikhwama sesitsha siwuhlobo lokuqaphela iyunithi yesitsha, futhi siwuhlobo lwesitsha sokupakisha esiguquguqukayo.Isetshenziswa kakhulu ekudleni, okusanhlamvu, imithi, amakhemikhali, imikhiqizo yamaminerali kanye nezinye izimpushana, i-granular, i-block izimpahla zokuthutha kanye nokupakishwa.Kukhona futhi izinhlobo eziningi zezikhwama zeziqukathi, izikhwama zendwangu ezimboziwe ezivamile, izikhwama zendwangu ye-resin, izikhwama eziyinhlanganisela nokunye.Ngakho-ke, hlobo luni lwendawo lapho izikhwama zeziqukathi zisetshenziswa?Ingakanani izinga lokushisa elingamelana nezikhwama zesitsha?Landelani i-Xiaobian ndawonye ukuze niyiqonde!
Isikhwama sesitsha izinto zokusetshenziswa
Isiqukathi siyisitsha sepulasitiki esiguquguqukayo esine-polypropylene kanye ne-polyethylene resin njengezinto zokusetshenziswa, ivolumu yayo engaphansi kuka-3m3 futhi isisindo esithwalayo singaphansi noma silingana namathani angu-3.
i-polypropylene
Iphuzu lokuncibilika lingu-165℃, lithamba cishe ku-155℃;
Izinga lokushisa lokusebenza lisukela ku -30°C kuya ku-140 °C.
Ingamelana nokugqwala kwe-asidi, i-alkali, isixazululo sikasawoti kanye nezinhlobonhlobo zezinyibilikisi eziphilayo ezingaphansi kuka-80℃, futhi ingabola ngaphansi kwezinga lokushisa eliphezulu kanye ne-oxidation.
i-polythene
Iphuzu elincibilikayo 85 ℃ kuya ku-110 ℃, elinokumelana okuhle kakhulu kwezinga lokushisa eliphansi;
Izinga lokushisa lokusetshenziswa lingafinyelela ku-100°C kuya ku-70°C, ukuzinza okuhle kwamakhemikhali, ukumelana ne-asidi eningi kanye nokuguguleka kwesisekelo (okungamelani ne-asidi enezakhiwo ze-oxidizing)
Izinga lokushisa lokusebenzisa isikhwama sesitsha?
Ingakanani izinga lokushisa lezikhwama zesitsha ezenziwe nge-polypropylene ne-polyethylene?
Ngokusho kwe-GB/T10454-2000 ejwayelekile kazwelonke, izinga lokushisa lokuhlola ukumelana nokubanda kwesikhwama sesitsha lingu -35℃.
Beka isikhwama sesitsha ebhokisini lokushisa elingaguquki -35℃ amahora angaphezu kwama-2, bese ugoqa umkhiqizo wokuhlola ube uhhafu ukuya kuma-degree angu-180 ukuze uhlole ukuthi i-substrate material yonakele, iqhekekile kanye nezinye izimo ezingavamile.
Izinga lokushisa lokuhlola ukumelana nokushisa ngu-80 ℃.
Faka umthamo ongu-9.8N emkhiqizweni wokuhlola bese uwubeka kuhhavini ongu-80℃ ihora elingu-1.Ngokushesha ngemva kokukhipha umkhiqizo wokuhlola, hlukanisa izingcezu ezimbili zokuhlola ezigqagqene futhi uhlole indawo engaphezulu ukunamathela, ukuqhekeka nezinye izimo ezingavamile.
Ngokwezinga lokuhlola, isikhwama sesitsha singasetshenziswa endaweni ephakathi -35 ° C kuya ku-80 ° C, kodwa asinconywa ukuthi sisetshenziswe isikhathi eside ezindaweni eziphakeme neziphansi zokushisa.
