Ulawulo lomgangatho luyimfuneko kulo naliphi na ishishini, kwaye abavelisi abalukiweyo abanjalo. Ukuqinisekisa umgangatho weemveliso zabo, abavelisi beengxowa eziphothiweyo kufuneka balinganise ubunzima kunye nobukhulu belaphu labo rhoqo. Enye yeendlela eziqhelekileyo ezisetyenziswayo ukulinganisa oku yaziwa ngokuba yi-'GSM' (iigram nge-square meter).

Ngokuqhelekileyo, silinganisa ubukhulu bePP ilaphu elukiweyokwi-GSM. Ukongeza, iphinda ibhekisele kwi "Denier", ekwasisalathisi somlinganiselo, ngoko siguqula njani ezi zimbini?

Okokuqala, makhe sibone ukuba iGSM kunye neDenier zithetha ukuthini.

1. Yintoni i-GSM yezinto ezilukiweyo zepp?

Igama elithi GSM limele iigram nge square meter. Yiyunithi yokulinganisa esetyenziselwa ukumisela ubukhulu .

2. Yintoni iDenier?

I-Denier ithetha i-fiber grams nge-9000m nganye, yinxalenye yomlinganiselo osetyenziswayo ukumisela ukutyeba kwefayibha zemisonto nganye okanye imicu esetyenziswa ekudaleni amalaphu namalaphu. Amalaphu anenani eliphezulu le-denier athande ukuba ngqindilili, omelele, kwaye omelele. Amalaphu anenani eliphantsi le-denier athande ukuba mhlophe, athambileyo, kwaye abe silky.

Emva koko, masenze ubalo kwimeko yokwenyani,

Sithatha umqulu we-polypropylene tape (umsonto) ukusuka kumgca wokuvelisa we-extruding, ububanzi be-2.54mm, ubude be-100m, kunye nobunzima be-8grams.

I-Denier ithetha umsonto ngeegram nge-9000m nganye,

Ngoko ke, iDenier=8/100*9000=720D

Qaphela:- Ububanzi beTape(Umsonto) abuqukwanga ekubaleni iDenier. Njengoko kwakhona ithetha umsonto ngeegram nge-9000m, nokuba bubuphi na ububanzi bomsonto.

Xa uthunga lo msonto ube yi-1m*1m yesikwele selaphu, masibale ukuba ubunzima buyakuba yintoni nge-square meter (gsm).

Indlela yoku-1.

GSM=D/9000m*1000mm/2.54mm*2

1.D/9000m=iigrams ngemitha ubude

2.1000mm/2.54mm=inani lomsonto ngemitha (iquka i-warp kunye ne-weft ngoko *2)

3. Umsonto ngamnye ukusuka kwi-1m*1m ubude be-1m, ngoko ke inani lomsonto likwangubude obupheleleyo bomsonto.

4. Emva koko ifomula yenza i-1m * 1m yelaphu yesikwere ilingane nomsonto omde.

Iza kwifomula eyenziwe lula,

I-GSM=UDENIER/UBUNZI BOMNTU/4.5

I-DENIER=GSM*UBUNZI BABANZI*4.5

Phawula: Isebenza kuphelaIingxowa ezilukiweyo zePPishishini lokuluka, kwaye i-GSM iya kuvela ukuba ilukwe njengeengxowa ezichasene nokutyibilika.

Kukho izibonelelo ezimbalwa zokusebenzisa i-GSM calculator:

1. Unokuthelekisa ngokulula iintlobo ezahlukeneyo zelaphu elilukiweyo le-pp

2. Ungaqinisekisa ukuba ilaphu olisebenzisayo likumgangatho ophezulu.

3. Unokuqinisekisa ukuba iprojekthi yakho yoshicilelo iya kuphuma kakuhle ngokukhetha ilaphu elineGSM efanelekileyo kwiimfuno zakho.
