Iintambo ezimelana nobushushu obuphantsi (ezidla ngokubizwa ngokuba "ziintambo ezingangeni kubanda") luhlobo lweentambo ezikhethekileyo ezenzelwe iindawo ezishushu kakhulu. Isiseko sazo sixhomekeke ekusebenziseni izixhobo ezikhethekileyo ezimelana nobushushu obuphantsi, ezizivumela ukuba zigcine iipropati zombane nezoomatshini ezintle naphantsi kweemeko ezinzima ezingaphantsi kwe -40°C ukuya kwi -60°C. Ngokwahlukileyo koko, iintambo eziqhelekileyo zifumana ukonakala kokusebenza ngokukhawuleza kwiindawo ezinjalo kwaye azinakuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo.
1. Umahluko osisiseko: Ukukhetha izinto
Izinto zezona zinto ziphambili ezibangela ukumelana nobushushu obuphantsi kwentambo, nto leyo ebonakala kakhulu kwi-insulation kunye ne-sheathing.
Izixhobo zokuvala ubushushu
Iintambo Ezingashukumiyo Kubushushu Obuphantsi: Sebenzisa izixhobo ezikhethekileyo zokukhusela ezifana ne-fluoropolymers, i-Polyurethane (PU), i-PVC eguqulweyo kubushushu obuphantsi, kunye ne-Cross-Linked Polyethylene (XLPE) yobushushu obuphantsi. Ezi zinto zinezakhiwo ze-molecular ezinokuguquguquka kubushushu obuphantsi, ukuqinisekisa ukuba umaleko wokukhusela awuqhekeki okanye awunciphi phantsi kweemeko ezibandayo kakhulu.
Iintambo eziQhelekileyo: Ngokwesiqhelo zisebenzisa i-PVC eqhelekileyo okanyeI-XLPE, eqina ngokukhawuleza kwaye iqhekeke kumaqondo obushushu aphantsi, nto leyo ekhokelela ekungasebenzini kobushushu.
Izixhobo zokugquma
Iintambo Ezingashukumiyo Kubushushu Obuphantsi: Isiciko sangaphandle sidla ngokusebenzisa iNitrile Rubber, iChloroprene Rubber (CR), iEPDM, iThermoplastic Polyurethane (TPU), okanye ezilungiselelwe ngokukodwa ubushushu obuphantsi.Izixhobo ze-LSZHEzi zinto azimelani nobushushu obuphantsi kuphela kodwa zikwabonelela ngokumelana nokukrala okugqwesileyo, ukumelana neoyile, ukumelana ne-UV, kunye nokumelana nemozulu, zibonelela ngokhuseleko olupheleleyo lwentambo.
Iintambo eziQhelekileyo: Isiciko senziwe kakhulu ngePVC okanye iPolyethylene (PE) eqhelekileyo, ethanda ukwaluphala nokuqhekeka phantsi koxinzelelo oludibeneyo lwamaqondo obushushu aphantsi kunye neendawo ezintsonkothileyo, ilahlekelwa ngumsebenzi wayo wokukhusela.
2. Umahluko kwiSakhiwo nakwiNdlela yokusebenza
Ngokusekelwe kwiimpawu zezinto eziphathekayo, ezi ntlobo zimbini zeentambo zibonisa umahluko omkhulu kuyilo lwesakhiwo kunye nokusebenza kokugqibela.

Ulwakhiwo: Ubude bokubeka obuphuculweyo kunye nokongezwa okunokwenzeka kweefayibha zokutsala, iileya ezichasene nokujija, okanye iileya ze-buffer ukuphucula ukugoba, ukujika, kunye nokumelana nempembelelo, ezifanelekileyo ukusetyenziswa kokushukuma.
Iintambo eziQhelekileyo: Esi sakhiwo senzelwe ukufakwa okungashukumiyo kumaqondo obushushu aphakathi, kunye nokuguquguquka okuphantsi kokunamathela komqhubi kunye nokuqina okuncinci koomatshini.
Uthelekiso lweNtsebenzo oluPhambili
Iintambo Ezingashukumiyo Kubushushu Obuphantsi:
Ukusebenza kakuhle koomatshini: Igcina ukuguquguquka okuphezulu, amandla aphezulu okutsalwa, kunye nokumelana nokudinwa okugobileyo nokuba kubanda kakhulu.
Ukusebenza koMbane: Iyakwazi ukugcina ukumelana okuzinzileyo kobushushu kunye namanqanaba okumelana nombane, kunye nokuqhuba kakuhle kombane.
Ukunyamezelana Kwendalo: Iyakwazi ukumelana nokugruzuka okugqwesileyo, ukumelana nokugruzuka ngamakhemikhali, kunye nokumelana nemozulu.
Iintambo ezisemgangathweni:
Ukusebenza Koomatshini: Ilahlekelwa bububhetyebhetye xa kushushu kakhulu; ishelufu kunye nobushushu buyaqhekeka, nto leyo eyenza ukuba zibe sengozini enkulu yokonakala koomatshini.
Ukusebenza koMbane: Ukumelana nobushushu kuncipha kakhulu, umngcipheko wokonakala uyanda, nto leyo ebangela iingozi ezinkulu zokhuseleko.
3. Iimeko zokusetyenziswa kunye neengcamango zoqoqosho
Umahluko ekusebenzeni umisela ngokuthe ngqo amasimi asetyenziswayo kunye nokuphila kakuhle kwezoqoqosho.
Imizekelo yesicelo
