Ko ingancin PCB tawada yana da kyau, bisa manufa, ba shi yiwuwa a rabu da haɗuwa da manyan abubuwan da ke sama. Kyakkyawan ingancin tawada shine cikakkiyar bayyanar kimiyya, ci gaba da kare muhalli na dabara. Yana nunawa a cikin:

Danko shine taƙaitaccen danko mai ƙarfi. Gabaɗaya ana bayyana ta danko, wato, ƙarfin juzu’i na kwararar ruwa da aka raba ta hanyar saurin gudu a cikin alkiblar maɗaurin ruwa, ƙungiyar ƙasa da ƙasa ita ce Pa/sec (Pa.S) ko milliPascal/sec (mPa.S). A cikin samar da PCB, yana nufin yawan ruwan tawada da sojojin waje ke samarwa.

Alakar juzu’i na sashin danko:

1Pa. S=10P=1000mPa. S=1000CP=10dpa.s

Plasticity yana nufin cewa bayan tawada ta lalace ta hanyar ƙarfin waje, har yanzu yana riƙe da kayansa kafin nakasu. Plasticity na tawada yana da amfani don inganta daidaiton bugu;

Tawada thixotropic (thixotropic) gelatinous ne lokacin da yake tsaye, kuma danko yana canzawa lokacin da aka taɓa shi. Hakanan ana kiransa thixotropic da anti-sagging;

Fluidity (mataki) Matsayin da tawada ke yadawa a ƙarƙashin aikin ƙarfin waje. Fluidity shine madaidaicin danko, kuma ruwa yana da alaƙa da filastik da thixotropy na tawada. Plasticity da thixotropy suna da girma, yawan ruwa yana da girma; ruwa yana da girma, alamar yana da sauƙi don fadadawa. Ƙananan ruwa, mai sauƙin bayyana netting, yana haifar da sabon abu na samuwar tawada, wanda kuma aka sani da netting;

Viscoelasticity yana nufin iyawar tawada da aka yanke kuma aka karye bayan an goge tawada da matsi don dawowa da sauri. Ana buƙatar saurin nakasar tawada yana da sauri kuma tawada ta sake komawa da sauri don zama da amfani ga bugu;

Rashin bushewa yana buƙatar tawada ya bushe akan allon a hankali a hankali, kuma ana fatan cewa bayan an canza tawada zuwa ƙasa, da sauri mafi kyau;

Girman fineness pigment da m kayan barbashi, PCB tawada gaba ɗaya kasa da 10μm, kuma girman fineness ya zama kasa da daya bisa uku na raga bude;

Lokacin da ake amfani da shebur tawada don ɗaukar tawada, matakin da tawada na filamentous ba ya karye idan an miƙe shi ana kiransa stringiness. Fil ɗin tawada yana da tsayi, kuma akwai filaye da yawa a saman tawada da farfajiyar bugu, waɗanda ke sanya ma’auni da farantin bugu ya zama ƙazanta har ma ya kasa bugawa;

Gaskiya da ikon ɓoye tawada

Don tawada na PCB, gwargwadon amfani da buƙatu daban-daban, ana kuma gabatar da buƙatu daban-daban don bayyana gaskiya da ɓoye ikon tawada. Gabaɗaya magana, tawada masu kewayawa, tawada masu ɗawainiya da tawada masu hali duk suna buƙatar babban ƙarfin ɓoyewa. Juriya mai siyar ya fi sassauƙa.

Chemical juriya na tawada

PCB tawada suna da tsauraran matakan acid, alkali, gishiri da kaushi bisa ga manufar amfani;

Juriya ta jiki tawada

PCB tawada dole ne ya hadu da juriya na karce na waje, juriya na girgiza zafi, juriya na kwasfa na inji, kuma ya dace da buƙatun aikin lantarki daban-daban;

Tsaro da kare muhalli na tawada

Ana buƙatar tawada na PCB don zama ƙasa mai guba, mara wari, aminci kuma abokantaka na muhalli.

A sama mun taƙaita ainihin kaddarorin tawada PCB goma sha biyu. Daga cikin su, a cikin ainihin aikin bugu na allo, matsalar danko yana da alaƙa da mai aiki. Danko yana da matukar mahimmanci ga santsi na siliki. Sabili da haka, a cikin takaddun fasaha na tawada na PCB da rahotannin QC, danko yana da alama a fili, yana nuna ƙarƙashin wane yanayi da irin nau’in kayan gwaji na danko don amfani.

A zahirin aikin bugu, idan dankowar tawada ya yi yawa, zai yi wuya a buga shi, kuma gefuna na zane-zanen za su yi jajir sosai. Don inganta tasirin bugu, za a ƙara mai bakin ciki don sa danko ya dace da bukatun. Amma ba shi da wahala a gano cewa a lokuta da yawa, don samun madaidaicin ƙuduri (ƙuduri), komai danko da kuke amfani da shi, har yanzu ba shi yiwuwa a cimma. me yasa? Bayan bincike mai zurfi, an gano cewa dankon tawada muhimmin abu ne, amma ba shi kadai ba. Akwai wani abu mai mahimmanci-thixotropy. Hakanan yana shafar daidaiton bugu.
