Featuring high-pressure resistance, yooj, thiab abrasion tsis kam, lawv yog dav siv nyob rau hauv vaj teb watering, ua liaj ua teb irrigation, industrial fluid transmissions, thiab domestic dej xa. Lawv kev tsim khoom ua raws li tus qauv tsim, txuas ntxiv extrusion thiab braiding ntau lawm txheej txheem, nrog rau cov txheej txheem nruj tswj xyuas kom muaj kev ruaj ntseg thiab kev pabcuam kev ua haujlwm. Cov txheej txheem tsim cov ncauj lus kom ntxaws yog raws li hauv qab no:
1. Raw Material Proportioning thiab Mixing
High -kev tsim cov hose zoo pib nrog cov khoom sib xyaw thiab sib xyaw ua ke. Cov ntaub ntawv tseem ceeb muaj xws li PVC resin hmoov, plasticizers, stabilizers, lubricants thiab anti-aging additives, uas yog proportioned raws li hose specifications thiab daim ntawv thov scenarios. Tag nrho cov ntaub ntawv raug siab - ceev kub sib tov rau tag nrho fusion, ces txias thiab khaws cia rau hauv silos tiv thaiv agglomeration, stabilizing tom qab extrusion zoo.
2. Inner Tube Extrusion thiab Shaping
Cov khoom sib xyaw PVC yog melted thiab homogenized nyob rau hauv ib qho - ntsia hlau extruder, ces extruded los ntawm ib tug mob siab rau tuag los ua ib tug du, uniform hollow puab raj. Lub raj kub sab hauv yog tam sim ntawd txias thiab zoo li tus nyob rau hauv lub circulating dej tank los kho cov yeeb nkab txoj kab uas hla thiab roundness thiab tsis txhob deformation. Ib qho tas mus li - nrawm nrawm- tawm lub tshuab ua kom cov phab ntsa hauv phab ntsa tuab thiab qhov sib npaug.
3. Intermediate Fiber Reinforcement Braiding
Raws li cov txheej txheem tseem ceeb txiav txim siab hose siab thiab tensile tsis kam, fiber ntau braiding qhwv siab -lub zog polyester yarn nyob rau hauv ib tug uniform crisscross los yog kauv mesh nyob ib ncig ntawm lub preheated puab raj. High - cov cuab yeej braiding ceev ua kom ntom ntom, txawm tias cov xov paj tsis sib tshooj lossis tsis ua haujlwm. Cov xov paj thickness thiab braiding ceev tau hloov kho rau siab - siab hoses, thiab preheating txhim kho kev sib raug zoo ntawm cov fiber ntau txheej thiab cov raj sab hauv los tiv thaiv delamination.
4. Kev kho cua sov ua ntej txheej txheej Extrusion
Lub braided semi- tiav hose raug xa mus rau qhov tsis tu ncua - qhov kub thiab txias preheating qhov cub kom tshem tawm cov av noo thiab me ntsis soften lub fiber mesh thiab lub raj sab hauv. Cov kauj ruam no ua rau cov khoom siv PVC sab nrauv tuaj yeem nkag mus rau hauv fiber ntau qhov sib txawv thaum lub sij hawm tom ntej txheej, kom tsis txhob interlayer delamination thiab tsim ib qho kev sib xyaw ua ke.
5. Txheej PVC Txheej Extrusion thiab Txheej
Qhov thib ob extruder tsho tiv no huab cua, abrasion thiab UV-cov khoom siv PVC tiv taus tusyees hla fiber ntau braided txheej ntawm precision tuag. Cov txheej PVC txheej tag nrho encapsulates thiab sau cov fiber ntau mesh, integrating lub puab raj, fiber reinforcement thiab txheej tiv thaiv txheej tag nrho. Txheej txheej thickness yog nruj me ntsis tswj kom sib npaug ntawm hose qhov yooj thiab hnav tsis kam.
6. Secondary Cooling thiab zaum kawg Shaping
Lub hose coated tshiab nkag mus rau hauv lub tank dej thib ob kom ua kom txias thiab khov ntawm peb - txheej txheej. Qhov no tshem tawm kev ntxhov siab sab hauv los ntawm extrusion thiab braiding, kom ruaj khov roundness, uniform phab ntsa thickness thiab tsis deformation. Synchronized traction thiab extrusion speeds lav tag nrho qhov sib xws ntawm lub hose.
7. Nto Printing, Kho -Length Txiav thiab Sealing
Cov hoses txias tau txais kev luam tawm nrog cov lus qhia tshwj xeeb, cov qauv thiab cov ntaub ntawv tsim khoom. Tom qab ntawd lawv raug txiav mus rau hauv tus qauv ruaj ntev raws li cov neeg siv khoom xav tau. Cov yeeb nkab kawg tau txais thermal sealing los kaw cov xov paj hauv fiber ntau, tiv thaiv xov xoob, dej seepage thiab interlayer sib cais hauv kev siv.
8. Kev tshuaj xyuas cov khoom tiav thiab cov khoom ntim khoom Winding
Cov hoses tiav tau txais kev tshuaj xyuas zoo, suav nrog kev kuaj pom, kev txheeb xyuas qhov ntev thiab cov qauv ntsuas kev ntsuas siab kom ua tau raws li cov qauv kev lag luam. Cov khoom tsim nyog tau txais qhov txhab, sau npe thiab ntim khoom, thaum cov khoom tsis raug raug tshuaj xyuas thiab rov ua dua tshiab kom ntseeg tau tias lub Hoobkas tsim khoom zoo.
Txheej txheem Core yam ntxwv
Tag nrho cov txheej txheem tsim khoom paub txog kev tsim khoom siv hluav taws xob tas mus li, nrog rau peb - txheej txheej txheej nruj sib koom ua ke tag nrho. Cov txheej hauv PVC ua kom cov kua dej zoo, qhov nruab nrab fiber ntau braided txheej bears tensile thiab siab loads, thiab txheej PVC txheej muab los tiv thaiv - abrasion, tiv thaiv - UV thiab tiv thaiv - tiv thaiv corrosion. Kev sib koom tes ntawm txhua tus txheej txheem ua kom ntseeg tau tias PVC fiber reinforced hose muaj qhov ua tau zoo, ua haujlwm siab thiab ua haujlwm ntev.
