Thaum tshav kub kub Fusion yog dab tsi?
Thaum tshav kub kub fusion melts cov yeeb nkab thiab haum qhov chaw. Lawv koom nyob rau hauv lub teeb siab. Cov ntaub ntawv sib xyaw ntawm qib molecular. Qhov no tsim ib daim monolithic. Qhov sib koom ua ke muaj zog npaum li cov yeeb nkab nws tus kheej. Nws yog kev sib txuas mus tas li.
Cov khoom siv rau vuam
PPR yog cov thermoplastic polymer. Nws softens ntawm ib ncig ntawm 260℃(500℃F). Nws tsis hlawv tam sim ntawm qhov no. Qhov no tso cai rau lub qhov rais ua haujlwm. Cov khoom melted ua viscous. Nws ntws los tsim ib lub foob zoo meej.
Critical Temperature Control
Lub tshuab vuam yuav tsum yog qhov tseeb. Qhov kub hloov pauv ua rau cov pob qij txha tsis muaj zog. Underheating ua rau tsis tiav fusion. Overheating degrades cov polypropylene. Ib txwm siv lub ntsuas kub ntsuas digital. Calibrate koj lub cuab tam tsis tu ncua.
Qhov tseem ceeb ntawm lub sijhawm cua sov
Lub sij hawm cua sov nyob ntawm cov yeeb nkab loj. Rau 20mm yeeb nkab, cua sov rau 5 vib nas this. Rau 25 hli, cua sov rau 7 vib nas this. Xa mus rau cov chaw tsim khoom daim ntawv qhia. Lub sij hawm pib thaum cov yeeb nkab / fitting yog tag nrho ntawm lub mandrel. Siv lub stopwatch rau precision.
Sib dhos thiab tuav sijhawm
Tom qab cua sov, tshem cov khoom sai sai. Koom nrog lawv hauv ib qho kev sib tw. Teem lawv zoo kawg nkaus yam tsis muaj twisting. Tuav lawv nyob rau hauv siab. Tuav rau lub sijhawm teev tseg. Qhov no tso cai rau thawj zaug solidification.
Txias Phase Chemistry
Cov saw hlau polymer re- entangle thaum lub caij txias. Cov txheej txheem no hu ua crystallization. Nws yuav siv ob peb feeb kom tiav. Tsis txhob cuam tshuam kev sib koom tes. External quab yuam lov cov tsim bonds. Tag nrho lub zog tsim tom qab txias.
Tshawb xyuas qhov zoo Weld Joint
Ib tug zoo weld tsim ib tug uniform hlaws. Cov hlaws tshwm nyob ib ncig ntawm lub caj dab haum. Nws yuav tsum sib npaug thiab tsis tu ncua. Tsis muaj qhov khoob lossis qhov tsis muaj qhov txaus. Lub hlaws loj yuav tsum sib phim specifications. Txiav thiab tshuaj xyuas ib qho piv txwv ua ntej.
Kev Nyab Xeeb Thaum Ua Haujlwm
Hnav- hnab looj tes tiv thaiv tshav kub. Ua haujlwm hauv qhov dej - qhov cua. Lub rhaub phaj yog kub heev. Khaws nws deb ntawm cov khoom siv hluav taws xob. Tsom ntsoov rau txoj haujlwm kom tsis txhob hlawv. Cia tag nrho cov cuab yeej txias ua ntej cia.
