Plastic Reinforced Kauv Hose feem ntau yog tsim los ntawm PVC los yog polyurethane ua ke nrog cov yas tawv kauv ribs. Nws cov khoom siv ua kom nruj nruj ntawm qhov chaw cia khoom, txheej txheej txheej, kub thiab av noo. Kev khaws cia tsis raug yuav ua rau tsis muaj kev puas tsuaj rau cov tsos, kev ncaj ncees thiab kev ua haujlwm ntawm kev ua haujlwm, cuam tshuam ncaj qha rau kev ua haujlwm ntawm kev ua haujlwm thiab kev xa khoom. Cov teeb meem no poob rau hauv peb pawg: ib puag ncig tsis zoo, kev coj ua tsis raug, thiab huab cua kub-humidity.
Ua ntej, sab nraum zoov cia nyob rau hauv lub hnub ncaj qha thiab hluav taws xob ultraviolet tsim teeb meem loj. Cov txheej txheej yas sab nrauv muaj txwv UV tsis kam. Tsis tu ncua ultraviolet hluav taws xob rhuav tshem cov yas molecular chains thiab accelerates cov khoom aging. Cov npoo tig daj thiab chalky, poob yooj, thiab tsim micro-cracks thiab tev. Raws li lub sij hawm cia nce, cov kab nrib pleb nthuav ntxiv thiab ua rau kom tawg los yog tawg thaum lub hose xa cov roj los yog kua. Meanwhile, ultraviolet hluav taws xob embrites kauv yas ribs, txo compression kuj thiab anti-deformation muaj peev xwm, yog li lub hose yog nquag mus flattening thiab vau nyob rau hauv lub tswv yim siv.
Qhov thib ob, qhov chaw ntub dej, dej-nplaum los yog qhov chaw tsis muaj cua tsis zoo yog tsis tsim nyog rau kev khaws cia. Thaum muab tso rau hauv av ntub, nyob rau hauv cov dej-logged zones, hauv qab daus los yog tsis saib xyuas warehouse ces kaum, lub hose tsis tu ncua absorbs noo noo. Pwm thiab moss loj tuaj rau ntawm qhov chaw thiab kis kab mob hauv lub cev hose. Cov dej noo nkag mus rau cov txheej txheem sib xyaw thiab ua rau muaj kev sib cais thiab delamination ntawm sab hauv thiab sab nrauv phab ntsa. Rau cov hoses haum nrog hloov cov yas kauv ribs, dampness ntev ua rau cov khoom oxidation thiab brittleness. Tsis tas li ntawd, cov plua plav thiab impurities yooj yim ua raws li cov av ntub thiab ua kom tawv dhau lub sijhawm, cov kab mob kis mus rau hauv kev pabcuam tom qab.
Thib peb, tsis tsim nyog stacking ua rau kev puas tsuaj. Over-height stacking nyob rau hauv hnyav loads, random folding thiab knotting yog ib qho yuam kev cia. Sustained hnyav siab quab yuam sab hauv kauv yas ribs rau hauv mus tas li distortion, tshem tawm thiab indentation. Sab hauv txoj kab uas hla shrinks thiab ntws passages ua obstructed. Kev ntxhov siab concentrates ntawm cov seem deformed, uas muaj kev cuam tshuam rau kev tawg thaum lub sijhawm ua haujlwm. Disorganized stacking kuj ua rau kev sib txhuam thiab khawb ntawm hoses. Kev tiv thaiv sab nrauv dhau los ua khawb thiab hnav, ua rau tsis muaj zog hnav thiab tiv thaiv corrosion.
Thaum kawg, qhov kub thiab txias cia ua rau muaj kev cuam tshuam tsis zoo. Kub-kub nyob rau hauv qhov chaw cia khoom softens cov ntaub ntawv yas, distorts hose profiles thiab impairs txhawb kev ua tau zoo. Kev cia txias sab nraum zoov ua rau cov phab ntsa yas nruj thiab nkig vim txo qis kev ua haujlwm molecular; tawg thiab tawg tuaj yeem tshwm sim txawm tias los ntawm kev sib cuag me me lossis khoov. Kev hloov pauv kub hnyav ua rau rov qab thermal expansion thiab contraction, aggravating khoom qaug zog. Kev pabcuam lub neej yog luv luv, kev ua haujlwm tsis txaus ntseeg tshwm sim thaum lub sijhawm ua haujlwm, thiab kev saib xyuas thiab hloov cov nqi nce.
