Kev Ua Liaj Ua Teb: Horticultural xyaum proves tias nroj tsuag nqus dej feem ntau los ntawm cov hauv paus hniav, thiab evaporation ntawm dej yog poob ntawm qhov saum npoo ntawm nplooj. Cov dej haus ntawm cov nroj tsuag nws tus kheej tsis loj heev. Piv txwv li, qhov saum npoo ntawm nplooj yog coated nrog ib tug dej-repellent tshuaj tsuag zaj duab xis, uas muaj peev xwm heev txo cov evaporation ntawm cov dej nyob rau saum npoo ntawm nplooj. Cov nroj tsuag yuav tsum muaj tsawg dua 50% ntawm lawv cov dej tag nrho. Txij li thaum xyoo 1960, cov tebchaws siv technology xws li Tebchaws Asmeskas tau siv txoj hau kev txau ntawm emulsified paraffin hauv kev ua liaj ua teb kom tiv thaiv cov ntoo, nroj tsuag, thiab lwm yam li ntawm kev poob dej thaum lub caij ntuj no dormancy los yog transplanting. Ntau cov patents rau kev ua lag luam emulsified paraffin. Emulsified paraffin yog siv rau:
(1) cog ntawm saplings. Ua ntej cog ntoo thuv thiab eucalyptus seedlings nyob rau hauv qus, lawv raug immersed nyob rau hauv emulsified paraffin. Tom qab txoj kev kho mob, cov ntoo saplings tau zoo tuaj yws hauv kev hloov cov nyom los sis kev nyab xeeb-siab phem huab cua. Lub ciaj nqi ntawm cov nplooj yog ho nce vim qhov txo evaporation ntawm dej nyob rau saum npoo ntawm nplooj.
(2) cog ntawm vaj tsev me. Thaum lub sij hawm qhov pruning los yog transplanting txheej txheem, tus ciaj sia taus tuaj yeem ua tau zoo dua los ntawm emulsifying paraffin. Yog hais tias ib tug loj pes tsawg tus shrubs yuav tsum tau transplanted thaum lub caij qhuav lub caij, pre-sprayed nrog emulsified paraffin saib kuas zoo hloov hlav.
(3) Tiv thaiv drought thiab preservation. Tom qab saplings thiab shrubs yog sprayed nrog emulsified paraffin, lawv muaj peev xwm tiv tau loj heev drought tej yam kev mob. Tom qab lub paj tau khaws cia, nws tuaj yeem ua ntej-soaked nyob rau hauv dej thiab ces kho nrog emulsified paraffin, thiab lub neej ntawm lub paj yuav muaj ntev heev.
Kev lag luam ntawv: Feem ntau ntawm daim ntawv xaiv cov txheej txheem nyob hauv nruab nrog nrog cov roj hmab hluav taws xob, uas ua rau lub yeeb yaj kiab ntawm daim ntawv muaj fiber ntau cov dej tsis huv. Cov voos tas li feem ntau siv resins, xws li emulsifying paraffin, uas tuaj yeem hloov tau 20% mus rau 40% ntawm cov pa luam yeeb. Ntxiv ntawm paraffin microemulsion tuaj yeem txo qhov hygroscopicity ntawm daim ntawv thiab txhawb qhov kev faib tawm ntawm cov pos hniav hauv cov qauv ntawm daim ntawv. Lwm cov txiaj ntsig ntawm kev ntxiv ntawm cov dej paraffin yog tias nws cuam tshuam cov teebmeem ntawm cov khoom siv sib xyaw nrog ntau cov pigments, kom cov ntawv luam tau zoo tuaj thiab kev luam ntawv zoo dua tuaj. Daim ntawv loj nyob rau hauv lub nraub qaum feem ntau yuav ua ntxiv thiab ua kom zoo dua los ntawm nws qhov chaw hauv npoo los yog txheej. Ntau yam tshiab ntawm emulsified paraffin yog tam sim no raug tsim los ua tus neeg sawv cev ntawm hydrophobic rau kev tsim cov ntawv qib siab.
