Ib qho ntawm cov yam ntxwv tseem ceeb ntawm PU Tube yog qhov elasticity siab thiab ua haujlwm nrawm, uas txawv ntawm cov yas zoo tib yam xws li PVC thiab PE. Raws li kev ua haujlwm feem ntau, lub hom phiaj - tshiab siab - zoo PU Tube tuaj yeem rov qab mus rau nws daim ntawv qub tom qab compression. Kev deformation tas mus li thiab rov qab tsis zoo tsuas yog tshwm sim hauv qhov xwm txheej tshwj xeeb. Qhov kev ua tau zoo rov qab yog txiav txim siab los ntawm plaub yam tseem ceeb: raj zoo, compression siv, compression ntev thiab aging℃ntawm lub raj.
Lub hom phiaj - tshiab tsim nyog PU Tube tsim los ntawm nkauj xwb polyurethane raw cov ntaub ntawv muaj ib tug compact molecular qauv thiab zoo heev elastic modulus, xa zoo heev deformation rov qab muaj peev xwm. Hauv cov xwm txheej ua haujlwm niaj hnub, kev sib zog me me, nrawm nrawm, me ntsis khoov thiab trampling ua rau lub cev deformation ib ntus, thiab cov raj tuaj yeem rov qab tsis pub dhau 3 vib nas this kom rov ua tiav nws txoj kab uas hla thiab cov yeeb nkab qub. Yuav tsis muaj kev nyuaj siab, creases los yog residual deformation, yog li cov kav dej thaiv thiab qhov nruab nrab ntws cuam tshuam yuav tsis tshwm sim. Txawm tias tom qab rov ua compression thiab dabtsi yog khoov cycles, lub raj tshiab tuav ruaj khov rebound kev ua tau zoo thiab qaug zog tsis kam, haum rau kev ua hauj lwm nrog nquag deformation.
Thaum compression quab yuam tshaj qhov chaw pib ntawm lub raj lossis compression yog khaws cia rau ntau teev, qhov kev ua tau zoo rov qab poob qis dua. Hnyav dov los ntawm cov khoom hnyav hnyav yuav hnyav rau lub raj phab ntsa. Yog hais tias lub xeev compressed no kav ntev li ntau teev, elastic molecular lug nyob rau hauv cov ntaub ntawv tsim ib ntus kev nyuaj siab qaug zog. Lub rebound qeeb thiab me ntsis indentations yuav nyob twj ywm tom qab rov qab. Cov mob no tsis sib npaug ntawm kev puas tsuaj mus tas li; lub raj feem ntau tuaj yeem rov qab tau qeeb tom qab sawv ntsug rau qee lub sijhawm thiab feem ntau tseem siv tau tom qab.
Tsawg-tus nqi PU Tube ua los ntawm cov khoom siv rov ua dua tshiab muaj qhov tsis muaj zog rov ua haujlwm. Cov raj no muaj ntau yam impurities thiab xoob molecular qauv, ua rau tsis zoo elasticity thiab toughness. Txawm tias me me compression ua rau qeeb rov qab, thiab kev tawg mus tas li thiab khoov deformation tshwm sim tom qab rov squeezing. Thaum deformed, lawv tsis tuaj yeem rov qab mus rau qhov qub, ua rau cov kav dej thaiv, tsis ruaj tsis khov ntawm huab cua thiab sealing tsis ua haujlwm, nrog rau lub neej luv luv.
Hnub nyoog PU Tube raug kev txom nyem ua tiav thiab tsis ua haujlwm ntawm kev ua haujlwm. Tom qab lub hnub raug tshav, siab - kub ua hauj lwm thiab ntev - lub sij hawm kev pab cuam, molecular chains tawg thiab elasticity yog ploj, tawm hauv cov ntaub ntawv nyuaj thiab nkig tsis muaj thawj yooj. Nyob rau theem no, lub raj tsis tuaj yeem thim rov qab tom qab compression tsis hais qhov kev sib tsoo hnyav, tsim cov indentations mus tas li, creases lossis txawm tawg. Lub raj xa dej tuaj yeem ua rau clogging, huab cua to thiab kua seepage. Tsis tas li ntawd, tsis yog -tus qauv nyias- phab ntsa PU Tube muaj qhov tsis muaj zog tiv thaiv - deformation muaj peev xwm piv nrog cov qauv tuab - cov phab ntsa thiab feem ntau yuav raug kev txom nyem tsis tiav rebound thiab mus tas li deformation.
Zuag qhia tag nrho, tsim nyog hom- qauv tshiab PU Tube muab ultra- cov yam ntxwv rov qab sai, ua rau nws nyiam cov khoom siv rau cov kav dej pneumatic thiab cov kav dej hloov pauv tau yooj yim. Tsuas yog muaj hnub nyoog, qis dua lossis dhau lawm - cov hlab compressed poob lub peev xwm rov qab los thiab tsim cov deformation mus tas li.
