Un grad ridicat de murd\u0103rie va reduce calitatea imprim\u0103rii. \u00cen imprimarea h\u00e2rtiei acoperite, a cartonului \u0219i a cartonului alb, \u00een special \u00een imprimarea color, efectul gradului de praf este deosebit de evident, afect\u00e2nd calitatea imprim\u0103rii.<\/p>\n

Aplica\u021bia de testare a murd\u0103riei pe h\u00e2rtie PDT-01<\/h2>\n

Testerul de murd\u0103rie din h\u00e2rtie PDT-01<\/strong>\u00a0este un kit de testare a pH-ului solului care con\u021bine 100 de benzi de testare cu un interval de 3,5-9. Benzile trebuie utilizate \u00een termen de 90 de zile de la deschidere \u0219i au un termen de valabilitate de doi ani.
\nIat\u0103 c\u00e2\u021biva pa\u0219i pentru testarea pH-ului solului:
\nColecta\u021bi probe de sol din diferite zone
\nSe amestec\u0103 o cantitate mic\u0103 de p\u0103m\u00e2nt cu ap\u0103 distilat\u0103
\nAtinge\u021bi h\u00e2rtia turnesol de solu\u021bia de sol-ap\u0103
\nCompara\u021bi culoarea h\u00e2rtiei de turnesol cu o diagram\u0103 de pH
\nDac\u0103 solul frizeaz\u0103 atunci c\u00e2nd se adaug\u0103 o\u021bet, este posibil s\u0103 fie acid
\n\u00cen cazul \u00een care solul nu frizeaz\u0103 atunci c\u00e2nd se adaug\u0103 bicarbonat de sodiu, acesta ar putea fi mai alcalin<\/h3>\n
