Txij li thaum xyoo 1840, thaum Fabkis tau ua thawj lub ntim cov xim hoses nrog cov tin, tin coated txhuas kav tau tshwm sim thaum Ntiaj Teb Tsov Rog Zaum 1, thiab cov kav dej txhuas tau tshwm sim hauv xyoo 1948. Cov hlau mos uas siv rau hauv cov khoom ntim khoom qub qub, xws li tin, txhuas. , aluminium, thiab lwm yam., muaj qhov tsis zoo ntawm kev ua corrosion-resistant thiab hnyav hnyav. Tsis ntev los no, nws tau maj mam hloov los ntawm cov yas hoses. Xyoo 1950, Switzerland tau tsim cov yas hoses ua los ntawm LDPE. Vim tsis muaj zog tiv thaiv permeability muaj peev xwm ntawm hoses ua los ntawm ib lub yas, lawv tsis haum rau ntim cov ntsiab lus uas yuav tsum tau airtightness zoo.
Hauv nruab nrab -1960s, cov hoses sib xyaw ua los ntawm ntau yam khoom tau tshwm sim hauv ntiaj teb. Cov hoses sib xyaw ua ke ua ke qhov zoo ntawm ob qho tib si hlau thiab yas, nrog cov khoom thaiv zoo, kev tiv thaiv corrosion, thiab kev puas tsuaj. Lawv kuj yog tus nqi qis thiab ua kom zoo nkauj, ua rau lawv nrov heev. Tuam Tshoj tau tsim cov yas sib xyaw hoses txij li xyoo 1972, thiab nyob rau hauv 30 xyoo dhau los, nws tau tsim sai heev, qhia ntau cov yas sib xyaw hose ntau lawm kab. Tam sim no, Tebchaws Asmeskas tau siv 10 lub hnab yas sib xyaw rau ib tus neeg, thaum Europe siv 12 hoses rau ib tus neeg. Xyoo 1983, kaum ib lub chaw tshuaj txhuam hniav thiab tshuaj pleev ib ce hauv Suav teb tau siv cov khoom ntim yas sib xyaw hose. Tam sim no, Tuam Tshoj lub peev xwm tsim khoom txhua xyoo nce mus txog 1.5 billion composite hoses.
Cov hoses sib xyaw tau pib siv rau kev lag luam xa cov kua dej hauv xyoo 1990s, rhuav tshem cov kev txwv yav dhau los thiab tau nthuav dav zuj zus.
Txhais ntawm Composite Hose
Composite hose yog lub thawv ntim tshwj xeeb uas tuav txoj haujlwm tseem ceeb hauv kev ntim khoom. Lub npe hu ua composite hose yog lub thawv ntim cylindrical ua los ntawm cov ntaub ntawv hloov tau yooj yim, uas yog folded thiab welded los ua ib lub thoob thiab muaj lub nozzle ntawm ib kawg. Tom qab extrusion, cov ntsiab lus yog nyem tawm los ntawm lub nozzle. Qhov no yog cov lus txhais tau teev tseg hauv "Cov Lus Qhia dav dav rau kev ntim khoom" hauv Tuam Tshoj tus qauv ntim khoom.
Lub ntsiab lus ntawm cov hoses sib xyaw yog maj mam dhau los ua dav dav, nrog ntau lub tuam txhab tsim cov hoses sib xyaw kom tau raws li qhov xav tau sib txawv thiab sib txawv ntawm lawv cov khoom.
Composite hoses yog resistant rau kim, high-temperature, flammable, explosive, corrosive, thiab environmentally polluting kua gases, nrog rau cov roj thiab tshuaj lom neeg. Txawm hais tias nws yog corrosive sulfuric acid, nitric acid, flammable thiab explosive solvents, composite hoses muaj kev ua tau zoo heev.
Composite hoses yog ua los ntawm ntau yam ntaub ntawv thiab muaj ntau txheej txheej sealing qauv. Lawv muaj kev tiv thaiv zoo rau kev tawg thiab tawg txawm nyob rau hauv qhov chaw hnyav tshaj plaws, thiab yuav tsis tawg sai sai. Lawv tuaj yeem yooj yim tswj kev sib kis ntawm cov roj av, diesel, roj av, thiab ntau yam kua tshuaj, thiab txawm tias muaj kev hloov pauv siab hauv huab cua txias.
Nws yog lub teeb nyob rau hauv qhov hnyav, muaj zog nyob rau hauv toughness, yooj yim rau lis, saj zawg zog nyob rau hauv kev siv, resistant rau kub, tsis tshua muaj kub, laus, deformation, corrosion, exposed puab kauv hlau thiab tshwj xeeb puab txheej, thiab muaj txhim khu kev qha hluav taws xob dissipation kev ua tau zoo.
Cov qauv ntawm ib hom tshiab ntawm kev sib xyaw hose
Lub cev hose yog tsim los ntawm ntau txheej txheej ntawm kev ua haujlwm polymer zaj duab xis thiab hluavtaws fiber ntau cov txheej txheem, nrog ob txheej ntawm kauv hlau xaim qhwv ruaj khov sab hauv thiab sab nraud. Nrog Siv TAIEN composite hose ua piv txwv classic (zoo ib yam li lwm cov hoses sib xyaw):
Internal kauv steel hlau: feem ntau stainless hlau, galvanized steel, aluminium alloy, polypropylene los yog TEFLON coated steel hlau;
Sab nraud kauv hlau hlau: yeej ua los ntawm stainless hlau los yog galvanized hlau;
Cov txheej txheej sab hauv: Xaiv cov yeeb yaj kiab ua haujlwm xws li Teflon Polietilene Nylon PET raws li cov yam ntxwv ntawm cov khoom siv thauj khoom, thiab siv cov cuab yeej siv los ua cov hose nrog ntau hom kua resistant sealing zog.
Txhim kho txheej thiab tiv thaiv kev laus txheej txheej: cov txheej txheem txhawb nqa lub zog muaj zog rau lub hose. Lub txheej txheej ntawm lub hose yog xim txheej txheej nrog kev puas tsuaj thiab kev laus ua haujlwm.
Classification ntawm composite hoses
Nrog rau txoj kev loj hlob sai ntawm cov hoses sib xyaw hauv kev lag luam, cov chaw tsim khoom tsim ntau yam ntawm cov hoses sib xyaw, uas tuaj yeem muab faib ua 7 pawg:
1. Ntau lub hom phiaj roj resistant composite hose, dav siv rau kev thauj cov roj, kua roj, roj av, diesel, kerosene, roj crude thiab lwm yam khoom siv hydrocarbon.
2. Ntau lub hom phiaj chemical conveying hose, dav siv nyob rau hauv qhov chaw uas corrosive tshuaj kua thiab roj khoom thauj, nrog rau cov tshuaj tiv thaiv zoo heev.
3. Automotive hose, tshwj xeeb tshaj yog tsim rau cov tsheb thauj khoom, yog mos thiab lub teeb yuag, haum rau kev khoov thiab txav mus los, nrog lub neej ntev tsim, thiab yog lub thoob ntiaj teb lees paub hose rau cov tsheb thauj khoom.
4. Dock nkoj thauj khoom thiab thauj khoom hose, tshwj xeeb tshaj yog tsim los rau cov nkoj thauj khoom, nrog rau cov qauv siv zog, cov khoom hnyav, cov tshuaj tiv thaiv zoo heev, thiab nquag khoov tsis tawg.
5. Xim thiab txheej conveying hose, uas yog tsim tshwj xeeb rau cov xim thiab cov khoom siv, yog hnyav resistant, hnav-resistant, thiab muaj cov khoom zoo heev antioxidant.
6. Tsis tshua muaj kub resistant hose, uas yog siv nyob rau hauv qis kub ib puag ncig los yog thauj cov khoom uas tsis muaj kub xws li ethylene, LPG, LNG, propane, qhuav dej khov, thiab lwm yam.
7. Cov hoses kub kub yog siv nyob rau hauv qhov chaw uas cov khoom kub thauj khoom, xws li dej kub thiab roj kub.
