Khad PCB waxaa loola jeedaa guddiga daabacaadda (guddiga wareegsan oo daabacan, oo loo yaqaan PCB) ee khadadka, astaamaha jireed ee muhiimka ah ee khadku waa dheef -shiid, thixotropy, iyo qurux. These physical properties need to be known to improve the ability to use ink.

PCB ink characteristics

1. Viscosity and thixotropy

Habka wax -soo -saarka guddiga wareegga daabacan, daabacaadda shaashadu waa mid ka mid ah hababka muhiimka ah ee lama huraanka ah. Si loo helo daacadnimada dhalmada sawirka, khadku waa inuu lahaadaa dheef wanaagsan iyo thixotropy ku habboon. Waxa loogu yeero isku-dheelitirka waa isku-dhaca gudaha ee dareeraha, taas oo macnaheedu yahay iyadoo la adeegsanayo ficilka xoogga dibedda, hal lakab oo dareere ah ayaa ku dul-dul-dhaca lakabka kale ee dareeraha ah, iyo xoogga isku-buuqa oo ay ku kacaan lakabka gudaha ee dareeraha. Dheecaan gudaha ah oo dareere ah oo dhumuc weyn ayaa la kulmay iska caabin farsamo oo weyn, iska caabin dareere khafiif ah ayaa ka yar. Viscosity waxaa lagu qiyaasaa barkadaha. In particular, it should be noted that temperature has a marked effect on viscosity.

Thixotropy waa hanti jir ahaaneed oo dareere ah, taas oo ah, isku -dheellitirka dareeraha ayaa hoos u dhacaya marka la kiciyo, isla markaana si dhakhso leh ayuu ugu soo celiyaa is -beddelkiisii ​​asalka ahaa ka dib markii uu istaagay. Marka la kiciyo, ficilka thixotropic wuxuu soconayaa muddo dheer oo ku filan si dib loogu habeeyo qaab -dhismeedkiisa gudaha. Si loo gaaro saamaynta daabacaadda shaashadda oo tayo sare leh, thixotropy khad aad bay muhiim u tahay. Gaar ahaan habka xoqidda, khadku waa la kiciyaa ka dibna wuxuu noqdaa dareere. Kaalintani waxay khadadka ku dardargelisaa xawaaraha mesh, waxay kor u qaadaa khadkii asalka ahaa ee khadkii kala duwanaa si siman ugu xirnaa hal. Marka uu xoquhu joojiyo dhaqaajinta, khadku wuxuu ku noqdaa xaalad aan caadi ahayn, isla markaana dheecaankiisu si dhakhso ah ayuu ugu noqdaa xogtii asalka ahayd ee loo baahnaa.

2. Ciriiri

Pigments iyo filtarrada macdanta guud ahaan waa kuwo adag, oo aad u yar oo cabbir ah oo aan ka badnayn 4/5 micron, oo sameeya xaalad qulqul isku mid ah qaab adag. Therefore, it is very important to require fine ink.

Nooca khad PCB

Qalinka PCB wuxuu inta badan u qaybsan yahay saddex xariiq, xannibaadda alxanka, khad dabeecad saddex nooc.

Qadka qadka waxaa loo isticmaalaa lakab caqabad ku ah si looga hortago daxalka qadka marka la qooqayo si loo ilaaliyo khadka, guud ahaan nooca xasaasiga ah ee dareeraha ah. There are two kinds of acid corrosion resistance and alkaline corrosion resistance, alkali resistance is more expensive, this layer of ink in the corrosion of the line uses alkali to dissolve it.

Qalinka alxanka waxaa lagu rinjiyeeyay xariiqda sida khad ilaalin ka dib laynka. Waxaa jira sawirro dareen -celin leh iyo kuleyl daaweyn, iyo noocyada adkaynta ultraviolet, ku hay suufka sabuuradda, qaybaha alxanka ee habboon, dahaarka, iyo iska -caabbinta oksaydhka.

Khadka astaamaha waxaa loo isticmaalaa in lagu sameeyo calaamadaynta dusha sare, sida calaamadaynta qaybaha qaybaha, guud ahaan caddaan.

Dhab ahaantii, waxaa jira khadyo kale, sida kool -siinta, waa in la sameeyo dahaadhka naxaasta ama daaweynta dusha uma baahna inay wax ka qabato qayb ka mid ah ilaalinta, ka dibna waa la jeexi karaa; Khad qalin iyo wixii la mid ah.

Isticmaalka khadadka PCB arrimaha u baahan feejignaan

According to the actual experience of the use of ink by most manufacturers, the use of ink must be carried out in accordance with the following provisions:

1. Si kastaba ha noqotee, heerkulka khadku waa inuu ka hooseeyaa 20-25 ℃, isbeddelka heerkulku ma noqon karo mid aad u weyn, haddii kale, waxay saamayn doontaa isku-dheelitirka khadadka iyo tayada daabacaadda shaashadda iyo saamaynta.

Gaar ahaan marka khadku dibadda lagu kaydiyo ama lagu kaydiyo heerkul kala duwan, waa in la dhigaa heerkulka deegaanka si uu ula qabsado dhawr maalmood ama loo sameeyo foostada khad si loo gaaro heerkulka ku habboon. Tani waa sababta oo ah adeegsiga khad qabow wuxuu sababi doonaa guuldarada daabacaadda shaashadda, taasoo keenta dhibaato aan loo baahnayn. Sidaa darteed, si loo ilaaliyo tayada khad, waxaa ugu wanaagsan in la kaydiyo ama lagu kaydiyo xaaladaha habka heerkulka caadiga ah.

2. Ka hor intaan la isticmaalin, khadku waa inuu ahaadaa mid si buuxda oo taxaddar leh gacanta ama si farsameysan si siman u kicin. Haddii khadku hawada gasho, isticmaal inaad istaagto muddo. Haddii loo baahdo dareere, marka hore si fiican isku walaaq ka dibna tijaabi dheef -shiidka. Foostada khadku waa in la xidhaa isla marka la isticmaalo ka dib. Isla mar ahaantaana, marna ha ku celin khadkii shaashadda foostada khad iyo khad aan la isticmaalin oo la isku daray.

3. Wakiilka nadaafadda oo si wanaagsan u isticmaalidda is -waafajinta labada dhinac ayaa qaadaya shabakad cad, waxayna rabaan inay si fiican u nadiifiyaan. When cleaning again, it is best to use a clean solvent.

4. Qallajinta khad, waa inay lahaataa nidaam dhammaystiran oo fiican aaladda.

5. Si loo joogteeyo xaaladaha hawlgalka waa inay buuxiyaan shuruudaha farsamo ee goobta qalliinka ee hawlaha daabacaadda shaashadda.

Waa maxay doorka khad PCB ee habka wax soo saarka PCB

Ink wuxuu kaalin ka qaataa soo saarista ilaalinta bireedka naxaas si maqaarka maqaarku aanu u soo bixin, wuxuu saamayn doonaa habka soo socda, khad xasaasi ah, saliid kaarboon, saliid lacag ah, iyo saliid kaarboon iyo saliid lacag leh waxay leeyihiin tabin ay sameeyaan, oo badiyaa loo isticmaalo midabka khad , saliid cad, saliid cagaaran, saliid madow, saliid buluug, saliid cas, subag.
