Iindlela zoVavanyo oluMgangatho lokulinganisa ukunamathela ngoVavanyo lweTape

Iindlela zoVavanyo zokulinganisa ukunamathela

Lo mgangatho ukhutshwa phantsi kobizo olusisigxina D 3359; Inani elilandela emva koko libonisa unyaka wokwamkelwa komntwana wokuqala okanye, kwimeko yohlaziyo, unyaka wohlaziyo lokugqibela. I-epsilon ephezulu (e) ibonisa utshintsho lomhleli ukususela kuhlaziyo lokugqibela okanye ukuvunywa kwakhona.

1. Umgangatho

1.1 Ezi ndlela zovavanyo zibandakanya iinkqubo zokuvavanya ukunamathela kweefilimu zokugquma zetsimbi i-substrates ngokufaka kunye nokususa i-tape-sensitive tape phezu kokusikwa okwenziwe kwifilimu.
1.2 Indlela yoVavanyo A yenzelwe ubukhulu becala ukuba isetyenziswe kwiindawo zemisebenzi ngelixa iNdlela yoVavanyo B ifaneleke ngakumbi ukusetyenziswa elabhoratri.Kwakhona, iNdlela yoVavanyo B ayithathwa njengefanelekileyo kwiifilimu ezityebileyo kune-5 mils (125μm).
QAPHELA 1—Kuxhomekeke kwisivumelwano phakathi komthengi nomthengisi, iNdlela yoVavanyo B inokusetyenziselwa iifilimu ezishinyeneyo ukuba kusetyenziswa izithuba ezibanzi.
1.3 Ezi ndlela zovavanyo zisetyenziselwa ukufumanisa ukuba ngaba ukuncamatheliswa kwentonga kwi-substrate kuhlobo lwemfuza.ralinqanaba elaneleyo. Abahluli phakathi kwamanqanaba aphezulu okubambelela apho kufuneka iindlela ezintsonkothileyo zokulinganisa.
QAPHELA 2-Kufuneka kuqatshelwe ukuba ukungafani kokubambelela kwi-coating surface kunokuchaphazela iziphumo ezifunyenweyo kunye neengubo ezinobumba obufanayo.
1.4 Kwiinkqubo ze-multicoat ukusilela ukubambelela kunokwenzeka phakathi kweedyasi ukwenzela ukuba ukunamathela kwenkqubo yokugqoka kwi-substrate kungamiselwa.
1.5 Amaxabiso achazwe kwii-SI units kufuneka athathwe njengomgangatho. Amaxabiso anikwe kwizibiyeli zezolwazi kuphela.
1.6 Lo mgangatho awufuni kujongana neenkxalabo zokhuseleko, ukuba zikhona, ezinxulumene nokusetyenziswa kwayo. Luxanduva lomsebenzisi walo mgangatho ukuseka ukhuseleko olufanelekileyo kunye neendlela zempilo kunye nokumisela ukusetyenziswa kwemida yokulawula ngaphambi kokusetyenziswa.

2. Amaxwebhu ekubhekiselwa kuwo

2.1 ImiGangatho ye-ASTM:

• D 609 Ukuziqhelanisa nokuLungisa iiPaneli zeNtsimbi eziQoqisiweyo zokuVavanya iPeyinti, iVanishi, iiNgqungquthela zoGuqulo, kunye neeMveliso eziNxulumeneyo zokuBamba2
• I-D 823 yeZenzo zokuVelisa iiFilimu zoButyebe obufanayo bePaint, iVarnish, kunye neMveliso eNxulumene nayo kwiiPaneli zoVavanyo.
• I-D 1000 yendlela yoVavanyo kwiiTapes eziNxibeleleyo eziNxibeleleyo eziSetyenziselwe ukuSebenza koMbane kunye ne-Electronic.
• I-D 1730 Iindlela zokuLungiselela i-Aluminiyam kunye ne-Aluminiyam-Alloy Surfaces ye-Painting4
• ISikhokelo se-D 2092 sokuLungiselela iZinc-Coated (iGalvanized) iSteel Surfaces for Painting5
• I-D 2370 yeNdlela yoVavanyo yeePropathi eziNyenzekayo zeNgqungquthela ye-Organic2
• I-D 3330 Indlela yokuvavanya i-Peel Adhesion ye-Tape ye-Pressure-Sensitive Tape 6
• I-D 3924 iNkcazo yeNdawo eMiselweyo yoMgangatho woBume kunye noVavanyo lwePeyinti, iVarnish, iLacquer, kunye nezinto eziNxulumeneyo
• I-D 4060 yoVavanyo lweNdlela yoVavanyo lwe-Abrasion yokuNchasa i-Organic Coatings yi-Taber Abraser

3. Isishwankathelo seeNdlela zoVavanyo

3.1 Indlela yoVavanyo A-I-X-cut yenziwe ngefilimu kwi-substrate, i-tape-sensitive tape isetyenziswe phezu kwe-cut and then isuswe, kwaye i-adhesion ihlolwe ngokusemgangathweni kwi-0 ukuya kwi-5 isikali.
3.2 Indlela yoVavanyo B-Iphethini ye-lattice ene-XNUMX okanye ishumi elinanye ukusikeka kwicala ngalinye lenziwe kwifilimu kwi-substrate, i-tape-sensitive tape isetyenziswe phezu kwe-lattice kwaye isuswe, kwaye ukunamathela kuhlolwa ngokuthelekisa kunye neenkcazo kunye nemifanekiso.

4. Ukubaluleka kunye nokusetyenziswa

4.1 Ukuba i-coating izalisekisa umsebenzi wayo wokukhusela okanye wokuhlobisa i-substrate, kufuneka ibambelele kuyo ubomi benkonzo obulindelekileyo. Ngenxa yokuba i-substrate kunye nokulungiswa kwayo komphezulu (okanye ukungabikho kwayo) kunefuthe elibi kakhulu kwi-adhesion of adhesion of coatings, indlela yokuvavanya ukunamathela kwengubo kwii-substrates ezahlukeneyo okanye unyango olungaphezulu, okanye kwiingubo ezahlukeneyo kwi-substrate efanayo kunye nonyango, oluluncedo olukhulu kushishino.
4.2 Ukuthintelwa kwazo zonke iindlela zokubambelela kunye nokuthintelwa okuthe ngqo kwale ndlela yovavanyo ukuya kumanqanaba asezantsi okubambelela (jonga i-1.3) kufuneka kuqatshelwe ngaphambi kokuyisebenzisa. Ukuchaneka kwe-intra- kunye ne-inter-laboratory yale ndlela yovavanyo iyafana nolunye uvavanyo olwamkelwe ngokubanzi lweesubstrates ezigqunyiweyo (umzekelo, iNdlela yoVavanyo D 2370 kunye neNdlela yoVavanyo D 4060), kodwa oku kuyinxalenye yesiphumo sokungabi naluvelwano kubo bonke. kodwa umahluko omkhulu ekunamatheleni. Isikali esilinganiselweyo se-0 ukuya ku-5 sikhethwe ngamabomu ukuphepha ingcamango yobuxoki yokuba buthathaka.
