Flatness yog ib qhov tseemceeb rau PA66 thermal break strips. Cov strips tsis muaj flatness yuav tsis sib nyiaj nrog lub aluminum window frames, cuab yuav sov thiab tsis nyob zoo. Txhawm rau PA66 thermal break strip manufacturer uas muaj R&D experience sedan 2006, peb paub tias xaiv tus rolling machine tseemceeb rau kev txhim kho flatness. Thru peb one stop service, peb sib sau nrog rolling machines nrog raw material production (twin screw granulation) thiab extrusion (single screw extruders) rau kev pab pawg PA66 strips.
PA66 thermal break strips ua raws li kab kev tshwm sim rau hauv qhov chaw ntawm lub frame aluminum. Yog tias muaj ib cheeb tsam hlo sib txawv—tsuas yog 0.1mm kuj los—yees nws tshwm sim kab ncaj kab rov tav thaum sau ua ke. Lawv kab no pab tso tshuaj kub dhau, txav thiab diminis effect insulation thermal ntawm lub strip txog 30%. Tom qab no, cov strips hlo sib txawv tso kom tswv yim tso ntau zog dua nyob rau hauv kev xaiv, uas tuaj yeem cuam rau lub strip lossis plua lub frame aluminum. Rau cov neeg tsim kho thiab cov neeg tsim khoom window, qhov flatness tsis zoo lead mus rau kev hloov kho dua, delays thiab nce ntau nqi.
Tom qhov PA66 tsheb nqus tshuab los extruded los ntawm single screw extruders (qhwv chaw pib rau qhov txoj kev no), lawv tsis tau muaj qhov sib txawv hauv qab zib ib yam xwb los ntawm kev sov dav hlau. Qhov rolling machine pressing qhov kub strips nyob saum precision rollers kom tshem tawm cov me me. Qhov rolling machine raug yuav tsum flatten qhov surface thiab tseem sau qhov structural integrity—tseem ceeb rau PA66 strips reinforced nrog glass fibers. Peb khw kho tshuab tshwj tsis sib txawv yog matching rolling machines rau peb extrusion lines, txiav txim siab tias txhua lub strip txhawis flatness standards (≤0.05mm deviation per meter).
Kev lag luam ntau yam (feem ntau yog 3 mus rau 5) yog qhov kev xaum zoo tshaj rau PA66. Sis tsis zoo li kev lag luam ib qhov, kev lag luam ntau yam siv kev ntxuav me me thiab zoo. Qhov thawj (nyob deb tshaj plaws rau qhov khaiv) ntxuav me me rau daim ntawm PA66 kom nws tau shap hluv hluv, thaum qhov tom ntej—nrog ntxuav ntau dua—thiaj pab ruaj nruaj txoj kab. Peb hloov kho ntxuav nyob rau hauv PA66: rau PA66 muaj roj fiberglass (qhov uas peb tsim loj tshaj), peb txhim kho ntxuav rau qhov thaum 0.8-1.2 MPa. Qhov no tiv thaiv kev puav tseg ntawm roj (uas tuaj yeem ua rau ceev npuag) thaum twb muab kom hluv hluv. Kev parallelism ntawm cov lag luam tau khoom los ntawm ±0.01mm, yog li tsis muaj qhov chaw twg ntawm daim uas tau ntxuav ntau dua lwm qhov.
Kev tsim tawb ntawm PA66 hlo li cas thaum khib nyiab txiav txim, yog li qhov chaw nruab nrhiav uas muaj khib nyiab tuaj yeem txiav txim yog yooj yim. Peb cov chaw nruab nrhiav muaj cov hlais uas muaj khib nyiab (thiab plua rau 80-100°C) uas sib xws nrog qhov chaw nruab nrhiav tso tawm khib nyiab. Yog tias qhov chaw nruab nrhiav tso khib nyiab tshaj li, nws yuav tsau thiab meej meem rau kev puag; yog tshaj khib nyiab, nws yuav rov tawv tsis zoo. Cov hlais uas muaj khib nyiab tuaj yeem tivthaiv qhov chaw nruab nrhiav nyob hauv qhov xwm yeem "plastic", kom qhov chaw nruab nrhiav tuaj yeem tshem tsov qhov tsis zoo tsis txhob puag. Cov hlais kuj muaj cov rooj sib thooj hauv nruab nrhiav kom tiv thaiv kev ntxoov ntxooj—qhov kev sib raug no tuaj yeem pabcuam kev sib xws hauv txhua qhov chaw nruab nrhiav.
Cov chawj sab nraud yog ib qhov me me tab sis tseem ceeb rau ib qhov siv tshuab rov teebj ntawm kev tsim khoom. Cov pa66 tuaj yeem hla siab hauv qab thaum tsim, thiab cov khoom tsis raug tso rau hauv qab rov teebj tuaj yeem ua rau sab nraud hla. Peb cov tshuab rov teebj muaj cov chawj sab nraud uas siv servo kom tswj lub taub ntawm cov pa66 nyob rau hauv yam sijhawm. Cov sensor tuaj yeem pom sab nraud ntawm cov pa66 thiab txhim kho cov chawj kom tso cov pa66 rau sab saum npoo, los ntawm no cov rov teebj tuaj yeem rov kho raws li sab (10-30mm, feem ntau rau cov thermal break strips). Qhov no tiv thaiv tus kheej 'wavy' sab nraud thiab tiv tauj kom cov pa66 muaj qhov loj thiab qhov plha txaus nyob rau sab txhua qhov.
Pej xeem PA66 yog tsim los ntawm kev siv ob lub screw extruders, uas faib cov kab roj zaum rau hauv polymer kom tsim tau qhov chaw tseem ceeb. Qhov chaw kab roj sib npoo no txhais tau tias pej xeem hlaws mus ua lub ntsiab lus zoo, tiag tiag—tab sis yog tshwj tsis pub tias tus hlaws tso tseg muaj kev nyuaj siab tsis zoo. Yog hais tias tus hlaws tso tseg muaj nyuaj siab tsis zoo yuav tshwm sim kev ruaj ntseg thiab tsis zoo. Tus hlaws tso tseg muaj kev nyuaj siab tshwm sim zoo: qhov chaw ntau hlaws tsim tau qhov hlaws tso tseg tsis muaj kev ruaj ntseg, txhim kho cov kab roj. Qhov kev sib cuag ntawm ob lub screw pej xeem thiab tus hlaws tso tseg precision tsim tau qhov hlaws tso tseg zoo, ruaj khov.
Xaiv: tshuab ntxuag roj ntxuag ib qhov thiab li yuav tsum tsim PA66 thermal break strips (tshuab ntxuag ob qhov yog rau granulation). Peb lub tshuab ib txhab rau kev pab tshuab rolling, uas txhaj tshuab ntxuag roj ntxuag ib qhov. Lub tshuab ntxuag roj ntxuag muab tso siab (2-5m/min rau PA66 strips) sib cuag nrog lub tshuab rolling muab tso siab—yog tshuab ntxuag roj ntxuag tso siab dua, lub tshuab rolling yuav tswj xyuas tom qab. Qhov no tiv thaiv “khiav” ntawm lub strip (uas tsim cov chaw me me thiab tsis zoo) lossis “ntsuas” (uas tsim cov chaw nyiag nyiag thiab nyiag dua). Qhov sib cuag zoo ntawm tshuab ntxuag roj ntxuag thiab tshuab rolling yog ib qhov tseem ceeb hauv peb lub tshuab ib txhab, tiv thaiv kev tsis sib xws uas tshwm sim rau cov neeg siv khoom uas nrhiav tshuab los ntawm ntau tus neeg muag.
Yog tias ib qhov kev pab txhua yam, peb tsis yog simply khaws cov roj kom zoo li—peb tso nws rau hauv qhov xav tau ntawm peb tus neeg siv khoom. Yog tias ib tug neeg siv khoom tsim cov PA66 hlau kub 20mm dav, peb hloov qhov dav ntawm roj kom zoo li, hloov qhov chaw ntxoov ntxoo thiab saem muaj pa rooj tswj kom raug rau qhov kev cai no. Peb kuj xa mus rau roj kom zoo li nrog rau peb cov khoom siv (cov roj ua los ntawm roj, cov roj kuaj mob), thiab pab pawg kev sib tham txog kev siv. Qhov no txhais tau tias cov neeg siv khoom tsis tas hire cov neeg paub ntau los tshuab xyuas lawv lub tshuab—peb ua tag nrho.
Pej xeem pej txhawm mus tshaj qhov siv. Peb muab kev pab cuam tshuam siv rau kev sib tshooj: sau hniav kom tshem tshaub PA66, kho cov rooj caij ntuas siab thiab kho cov rooj caij ntuas khaum. Peb kuj muab cov khoom siv los ntuas qhov ncig (xws li cov ntuas laser) uas cov neeg siv yuav siv los ntuas cov chaw tom qab khi. Yog tias cov neeg siv pom muaj teeb meem nrog qhov ncig, peb tus kws tshuaj yuav mus rau lub chaw ntawm tus neeg siv los kho qhov khi—yuav yog kho qhov sov lossis kho qhov caij ntuas. Qhov kev pab no tsoom tseg kom qhov khi tuaj yeem ua haujlwm zoo tshaj plaws, kom cov kheej muaj qhov zoo tshaj plaws.
Rau cov khaub ncaws siv los tshuab PA66 thermal break strip, tus tshuab rolling zoo li ntawm kev pab rau cov khaub ncaws zoo mus cuam tshuam mus rau cov khaub ncaws zoo dua. Peb muaj kev sib txuas ntawm tshuab rolling nrog ntau lub rooj, tuaj yeem sau nqi saum npoo, nrog kev coj mus sib xyaw nrog tshuab granules ob lub xov, tshuab extruders ib lub xov, thiab kev pab txhawb nqa tag nrho rau ib qhov chaw—pab rau pej xeem tau txais ib qhov kev daws teeb meem kom sai, ua rau cov khaub ncaws zoo hauv kev ua haujlwm. Nrog 17 xyli ntawm kev paub hauv cheeb tsheb, peb paub tias yuav ua li cas xaiv txhua qhov sib txuas hauv kev tsim khoom kom tau txais kev pab.
