Taw qhia thiab qhov zoo ntawm Ultrasonic yas txiav riam
Yuav luag tsis muaj kev sib cav txog txoj kev txiav ntoo. Txawm li cas los xij, txiav cov plastics (tshwj xeeb yog acrylic thiab polycarbonate) yog txawv kiag li. Vim yog ntau yam, yas txiav tej zaum yuav muaj ntau yam teeb meem nrog cov ntaub. Firstly, tshwj tsis yog koj coj ceev faj tsim nyog, qee yam plastics yuav yaj tau thaum lub sijhawm txiav. Tsis tas li ntawd, cov npoo yas yog nquag mus khawb thiab qee zaum yuav tsum muaj polishing ntawm cov npoo thaum ua tiav ntawm txoj haujlwm. Cov tshuaj ib txwm txiav tej zaum yuav muaj cov teeb meem tau hais los saum toj no hauv kev txiav yas.
Lub hauv paus ntsiab lus ntawm Ultrasonic kev txiav yog ho txawv ntawm cov txheej txheem txhua ib txwm txiav. Nws siv lub zog ntawm ultrasonic vuag rau tshav kub thiab yaj cov yas nto, yog li txiav cov yas khoom sib cais. Yog li no, ultrasonic txiav tsis tas yuav tsum tau txiav cov npoo lossis qhov tseem ceeb, uas yuav tsis ua rau mob pob txha lossis puas rau cov hniav sib chwv nrog cov khoom. Meanwhile, vim yog qhov kev co ntawm kev txiav ultrasonic, cov kev sib txhuam tsis yog tsawg heev, thiab cov khoom tom qab txiav tsis yooj yim ua rau cov hniav. Qhov no yog tshwj xeeb rau kev txiav cov hom phiaj viscous thiab zoo xws li khoom noj, roj hmab, thiab cov khoom uas nyuaj rau kev thov siab rau.
Yas yog cov khoom siv hluavtaws lossis cov khoom tsim tsim los ntawm kev sib txuas ob lossis ntau dua ntawm rau cov tshuaj polymer. Polymers lossis resins yog tshuaj sib xyaw ua ke lossis sib xyaw ua ke ntawm cov sib txuas ua ke, uas yog cov tshuaj lom neeg uas tau sib txuas ua ke los ua cov yeeb yaj kiab loj dua molecules.
Muaj ob txoj hauv paus ntawm cov polymers: thermosetting thiab thermoplastic. Ultrasonic yas txiav cov riam yog qhov haum rau txiav thermoplastic khoom. Thermosetting plastics yauv hloov pauv molecents hloov pauv thaum lub sijhawm ua, ua insoluble thiab melting. Lawv tsis tuaj yeem yaj lossis hloov pauv hauv lawv lub xeev kawg. Thermosetting plooj ntub yog qhov nyuaj thiab khib cov tshuaj uas ua rau thaum muaj cua sov. Yog li ntawd, thermosetting plooj thiab tsis haum rau ultrasonic los ua ke. Thermopoplastic ua softer thaum rhuab thiab nyuaj thaum txias, thiab tuaj yeem rov ua kom txias, thiab rov kho dua tshiab. Vim tias qhov tseeb tias cov txheej txheem ultrasonic sib dhos nyob ntawm cov khoom muag muag ntawm cov khoom siv, thermoplastic yog qhov haum rau ultrasonic los ua ke.
Polymer lwg me me yog cov saw ntev, nrog ib ntev uas yog 500 rau 10000 npaug ntau dua lawv cov tuab. Cov qauv molecular ntawm Thermoplastic kev txiav txim nws lub cev nqaij daim tawv zoo li nws melting thiab vuam cov yam ntxwv. Cov qauv molecular ntawm Thermoplastic tuaj yeem faib ua amorphous lossis semi crystalline. Random kev npaj ntawm cov lwg me hauv amorphous thermopastic. Ntawm qhov tsis sib xws, semi crystalline molecules muaj ib qho kev txiav txim siab thiab rov ua dua. Lub ntsiab amorphous thermopoplastic cov ntaub ntawv suav nrog abs, styrene, acrylic acid, pvc, thiab polycarbonate. The main semi crystalline thermoplastic materials include formaldehyde, nylon (polyamide), polyester, polyethylene, polypropylene, and fluoropolymers. Amorphoud cov ntaub ntawv tsis muaj qhov taw qhia melting. Tom qab cua sov, lawv hloov los ntawm lub xeev rigid (los ntawm cov duab hloov) mus rau lub hnab rubbery, thiab tom qab ntawd ntws hauv lawv qhov tseeb Molten State, maj mam ua softer. Kev kho kuj tseem kawm tau.
Zoo ntawm Ultrasonic Tej:
1. Cov hniav yuav ntxuav nws tus kheej, yog li yuav tsis muaj cov khoom txiav txuas rau cov hniav
2. Txo cov sij hawm los ntawm kev tu thiab luv luv lub sijhawm
3. Tsis muaj kev txiav siab tam sim no tuaj yeem tiv thaiv cov khoom deformation
4. Kev txiav txim siab zoo, yuav tsis tau qias neeg lossis so
5. Ib qho tseem ceeb ntawm ultrasonic txiav cov riam yog tias lawv tuaj yeem yog cov ntaub ntawv txiav uas nyuaj rau kev txiav
6. Lawv me me nyob rau hauv loj me, tsis tas yuav muaj ib cheeb tsam loj, thiab kuj tseem tuaj yeem muab tshuaj xuas tes rau ntau txoj haujlwm
